Mutant Human-pigs Created for Organs in U.S.

American researchers are using human stem cells and modified pig embryos to create a new life form dubbed "chimera" in order to cultivate a variety of human organs suitable for subsequent transplantation to humans.
“Our hope is that this pig embryo will develop normally but the pancreas will be made almost exclusively out of human cells and could be compatible for transplantation.”
-- Pablo J. Ross, Ph.D. Assistant Professor, University of California, Davis

“The organ would be an exact genetic copy of your liver but a much younger and healthier version . . .  With every organ we will look at what's happening in the [pig's] brain and if we find that it's too human like, then we won't let those foetuses be born.”
-- Walter Low, Department of Neurosurgery, University of Minnesota

“Chimeras will be seen to be what they are which is a saviour, given that they will provide, life-saving, sustaining organs for our patients.”
-- Scott Fahrenkrug, Recombinetics (a Minnesota-based company)

-- From "Scientists growing human pancreas inside 'mutant' pig in bid to solve transplant shortage" by Patrick Gysin, The Sun 6/5/16

The chimera embryos have been implanted in living sows and allowed to grow for 28 days before being tested and destroyed.

Pigs are thought to be an ideal biological incubator for growing human organs and could potentially be used to create hearts, livers, kidneys, lungs and corneas.

Critics say the experiment is “offensive to human dignity”.

From "US bid to grow human organs for transplant inside pigs" by Fergus Walsh, Medical Correspondent, BBC News 6/5/16

The team from University of California, Davis says they should look and behave like normal pigs except that one organ will be composed of human cells.

Creating the chimeric embryos takes two stages. First, a technique known as CRISPR gene editing is used to remove DNA from a newly fertilised pig embryo that would enable the resulting foetus to grow a pancreas.

This creates a genetic "niche" or void. Then, human induced pluripotent (iPS) stem cells are injected into the embryo. The iPS cells were derived from adult cells and "dialled back" to become stem cells capable of developing into any tissue in the body.

But the work is controversial. . . . The main concern is that the human cells might migrate to the developing pig's brain and make it, in some way, more human.

From "Scientists attempting to harvest human organs in pigs create human-pig embryo" by Nicola Davis and Kevin Rawlinson, UK Guardian 6/6/16

It was reported earlier this year that scientists had begun attempts to create the embryos, but there has been opposition from authorities. In September last year, the US National Institutes of Health said it would not back research into “chimeras” until it knew more about the implications.

Concerns have been raised about whether the transplantation of an organ from an animal into a human could risk introducing animal viruses into a patient. Researchers from Harvard Medical School, however, revealed last year that it was possible to use gene-editing technology to inactivate more than 60 retrovirus genes in pigs in a step towards such organ transplantation.

Prof George Church, who has led similar research into the possible use of chimeras, [said] “It opens up the possibility of not just transplantation from pigs to humans but the whole idea that a pig organ is perfectible.

“Gene editing could ensure the organs are very clean, available on demand and healthy, so they could be superior to human donor organs.”

Creating Synthetic Humans: Secret Harvard Meeting

On Tuesday, well over a hundred elite scientists were invited to discuss synthesizing the human genome — creating life from basic chemicals without biological parents, thus advancing beyond designer babies to creatures such as a synthetic Einstein (or Frankenstein).  Although the ethics of such advancement is controversial, what upset the greater scientific community and the media was their exclusion from the meeting.
“. . . would it be OK to sequence and then synthesize Einstein’s genome? If so how many Einstein genomes would it be OK to make and install in cells, and who could get to make and control these cells?”

3-Parent Babies are Ethical: Experts to Obama FDA

-- From "Secret Harvard meeting on synthetic human genomes incites ethics debate" by Joel Achenbach, Washington Post 5/13/16

Drew Endy, associate professor of bioengineering at Stanford University, and Laurie Zoloth, a professor of medical ethics and humanities at Northwestern University, published an essay this week raising questions about whether the gathering at Harvard had gone too far. After citing the beneficial possibilities of such research, they raised the thornier ethical questions . . .

Meanwhile, Marcy Darnovsky, executive director of the Berkeley, Calif.-based Center for Genetics and Society, a politically progressive organization that has had a skeptical view of biotechnology, issued a statement Friday criticizing the Harvard gathering: "If these reports are accurate, the meeting looks like a move to privatize the current conversation about heritable genetic modification."

From "Critics attack Harvard’s secret meeting on human genome synthesis" by Lisa M. Krieger, Santa Cruz Sentinel 5/14/16

The goal of the project — discussed Tuesday by an invitation-only group of about 130 scientists, lawyers, entrepreneurs and government officials from five continents — “would be to synthesize a complete human genome in a cell line within a period of 10 years,” according to the invitation.

Organizers included Harvard Medical School genetics Professor George Church and San Francisco-based Andrew Hessel of Autodesk’s Bio/Nano Research Group.

It portends a future with sci-fi implications, when a human genome — the complete set of genetic instructions for a human being — could be assembled like a Tinkertoy.

“Genomics is in the middle of four revolutions: sequencing, editing, synthesizing and understanding,” said Hank Greely, director of Stanford’s Center for Law and the Biosciences. “The first is well-advanced, the second coming on strong, the third just starting and the fourth — and most important — still scratching the surface.”

From "Scientists Talk Privately About Creating a Synthetic Human Genome" by Andrew Pollack, New York Times 5/13/16

Organizers said the project could have a big scientific payoff and would be a follow-up to the original Human Genome Project, which was aimed at reading the sequence of the three billion chemical letters in the DNA blueprint of human life. The new project, by contrast, would involve not reading, but rather writing the human genome — synthesizing all three billion units from chemicals.

But such an attempt would raise numerous ethical issues. Could scientists create humans with certain kinds of traits, perhaps people born and bred to be soldiers? Or might it be possible to make copies of specific people?

The project does not yet have funding, Dr. Church said, though various companies and foundations would be invited to contribute, and some have indicated interest. The federal government will also be asked. A spokeswoman for the National Institutes of Health declined to comment, saying the project was in too early a stage.

Right now, synthesizing DNA is difficult and error-prone. . . . But the cost and capabilities are rapidly improving. Dr. Endy of Stanford, who is a co-founder of a DNA synthesis company called Gen9, said the cost of synthesizing genes has plummeted from $4 per base pair in 2003 to 3 cents now. But even at that rate, the cost for three billion letters would be $90 million. He said if costs continued to decline at the same pace, that figure could reach $100,000 in 20 years.

From "Top scientists hold closed meeting to discuss building a human genome from scratch" by Ike Swetlitz, STAT 5/13/16

Synthesizing genomes involves building them from the ground up — chemically combining molecules to create DNA. Similar work by Craig Venter in 2010 created what was hailed as the first synthetic cell, a bacterium with a comparatively small genome.

In recent months, Church has been vocal in saying that the much-hyped genome-editing technology called CRISPR, which is only a few years old and which he helped develop, would soon be obsolete. Instead of changing existing genomes through CRISPR, Church has said, scientists could build exactly the genomes they want from scratch, by stringing together off-the-shelf DNA letters.

The topic is a heavy one, touching on fundamental philosophical questions of meaning and being. If we can build a synthetic genome — and eventually, a creature — from the ground up, then what does it mean to be human?

From "How Close Are We To An Entirely Synthetic Human?" by James Maynard, Tech Times 5/15/16

Human genomes are normally passed on from parent to child, transferring inheritable traits. Creating such a genome may be possible in as little as a decade, organizers of the meeting contend. However, even if the creation of such a genetic code transpired in the coming years, these sequences could only be placed within a cell to test the genome. This would still be a far cry from the creation of an entire synthetically-formed human being.

Once the technology is available to easily and inexpensively synthesize human genomes, a bevy of ethical dilemmas will present themselves. First, if it is possible to sequence and produce genomes of the best and brightest people in the world, how many copies of the same sequence should be produced, and who would be able to obtain them? Will parents who wish to raise a scientist be allowed to utilize genes patterned after famed physicist Albert Einstein? What about sports-minded parents who want a child with the baseball-related skills of Red Sox slugger David Ortiz?

Researchers are still a long way from the development of an entire synthetic human genome, however. The first man-made species, JCVI-syn1.0, was created in 2010.

Those people who worry about the development of this technology have a long time to wait before their fears may be realized, but that day is coming.

3-Parent Babies are Ethical: Experts to Obama FDA

Experts from the National Academy of Sciences, Engineering and Medicine are advising President Obama's Food and Drug Administration (FDA) to approve mitochondrial DNA replacement techniques (MRTs) to help about a hundred Americans give birth to creatures fabricated in a laboratory using genetic material from three unrelated people.  The experts promise that no scientists in the future will misuse the techniques to "play god" and create any Frankenstein babies.

-- From "Three-parent babies are ok, experts say" by NBC News 2/4/16

Such "three-parent" babies could be a way for people with a high risk of rare, devastating genetic diseases to have healthy children that are genetically their own, the National Academy of Medicine panel said.

And at first, the panel advised, only male embryos should be made this way until it's clear that dangerous mutations would not be passed down to future generations.

The FDA asked the academy, formerly known as the Institute of Medicine, to look at the three-person embryo processes, called mitochondrial replacement techniques (MRT). These are variations of in vitro fertilization, or IVF — the method that creates so-called "test-tube babies."

MRT adds a step [to IVF]: The mother's nuclear DNA would be removed and placed into the egg cell of another woman. The father's sperm would then be used to fertilize that hybrid egg.

The new techniques would be used to prevent the transmission of certain types of diseases that occur at the mitochondrial DNA level, the experts said.

From "Babies With Genes From 3 People Could Be Ethical, Panel Says" by Rob Stein, WBEZ-FM91.5 NPR (Chicago, IL) 2/3/16

Critics of the research, meanwhile, say the number of women who could benefit from the experiments is so small that it's not worth crossing a line that's long been considered off-limits — making genetic changes that could be passed down for generations.

"The possibility of what you could call 'mission creep' is very real," says Marcy Darnovsky, executive director of the Center for Genetics and Society, a watchdog group based in Berkeley, Calif. "People are talking about going forward not just with this but with the kind of genetic engineering that will produce outright genetically modified human beings."

Once that happens, Darnovsky says, "I think you get into a situation of where some people are genetically enhanced and other people are the regular old variety of human being. And I don't think that's a world we want to live in."

. . . The FDA email praised the "thoughtful work" of the panel and said the agency would be "reviewing" the recommendations. But it noted that the latest federal budget "prevents the FDA from using funds to review applications in which a human embryo is intentionally created or modified to include" changes that could be passed down to future generations. As a result, the email says, any such research "cannot be performed in the United States" at this time.

"I think it's a great step in the right direction," Mark Sauer, a professor of obstetrics and gynecology at Columbia University who is a member of one of the teams . . . "Politics as usual often gets in way of progress," Sauer said in a subsequent email. While the FDA statement would cause "undue delays" in his research, he added that he hoped it wouldn't permanently "necessarily halt the efforts."

From "Should scientists be allowed to change DNA to prevent genetic disease?" by Daphne Chen, Deseret News 2/3/16

"I think the field has come together to say, 'Let’s think about this together and go forward carefully,'" said Dr. Jeffrey Botkin, a professor of pediatrics and chief of medical ethics and humanities at the University of Utah.

Botkin sat on the 12-person committee that included top bioethics experts from Johns Hopkins, Caltech and Harvard.

"There's not a bright line between where this kicks over into unethical," [University of Utah, Department of Biochemistry Dr. Jared] Rutter said. "The technology that we have is expanding … more rapidly than our sophistication with thinking about how to use it."

From "Ethicists approve ‘3 parent’ embryos to stop diseases, but congressional ban remains" by Joel Achenbach, Washington Post 2/3/16

The committee, which was convened last year at the request of the Food and Drug Administration, concluded that it is ethically permissible to “go forward, but with caution” with mitochondrial replacement techniques (MRT), said the chairman, Jeffrey Kahn, a bioethicist at Johns Hopkins University.

But the advisory panel’s conclusions have slammed into a congressional ban: The omnibus fiscal 2016 budget bill passed by Congress late last year contained language prohibiting the government from using any funds to handle applications for experiments that genetically alter human embryos.

Thus the green light from the scientists and ethicists won't translate anytime soon into clinical applications that could potentially help families that want healthy babies, said Shoukhrat Mitalipov, a pioneer of the new technique at Oregon Health & Science University in Portland, Ore.

“It seems like the FDA is disabled in this case by Congress," Mitalipov said. “At this point we’re still not clear how to proceed."

From "Report: It's ethical to test embryos from DNA of 3 people" by Lauran Neergaard, Medical Xpress 2/3/16

The genes that give us our hair and eye color, our height and other family traits—and some common diseases such as cancer—come from DNA in the nucleus of cells, the kind we inherit from both mom and dad.

But only mothers pass on mitochondrial DNA, to both daughters and sons. It encodes a mere 37 genes, but defects can leave cells without enough energy and can lead to blindness, seizures, muscle degeneration, developmental disorders, even death. Severity varies widely, and researchers estimate 1 in 5,000 children may inherit some degree of mitochondrial disease.

Critics have argued that the first such births would have to be tracked for decades to be sure they're really healthy, and that families could try adoption or standard IVF with a donated egg instead. And they say it crosses a fundamental scientific boundary by altering what's called the germline—eggs, sperm or embryos—in a way that could affect future generations.

"It is reckless to proceed with this form of germline modification," said Marcy Darnovsky of the Center for Genetics and Society, an advocacy group.

UK's Frankenstein: Designer Babies OK'd by Gov't

Today, the British Human Fertilisation and Embryology Authority (HFEA) announced it authorized a private research firm to use abandoned babies, a.k.a. "leftover" embryos, to perform human genetic code editing.  Bioethicists have warned for years that such research will certainly lead to so-called "designer babies."
"This is the first step on a path that scientists have carefully mapped out towards the legalization of (genetically modified) babies."

-- From "Britain Okays Gene Editing Experiment on Human Embryos" by The Associated Press 2/1/16

Scientists say gene-editing techniques could one day lead to treatments for conditions like HIV, which causes AIDS, and inherited diseases like muscular dystrophy and sickle cell disease.

Peter Braude, an emeritus professor of obstetrics and gynecology at King's College London, said the mechanisms being investigated by [Dr. Kathy] Niakan and colleagues "are crucial in ensuring healthy, normal development and implantation" and could help doctors understand how to improve in vitro fertilization rates and prevent miscarriages.

The gene-editing technique was developed partly in the U.S. and scientists there have experimented with the method in animals and in human cells in the laboratory. Gene editing has not been used for any kinds of patient therapies yet.

Around the world, laws and guidelines vary widely about what kind of research is allowed on embryos, since it could change the genes of future generations. In the U.S., the National Institutes of Health cannot fund research on human embryos but private funding is allowed.

From "Britain gives scientists permission to genetically modify human embryos" by Rachel Feltman, Washington Post 2/1/16

The news comes less than a year after the first reports of human-gene editing — published by Chinese scientists in the journal Protein and Cell — using the fantastic and at times troubling technology known as CRISPR. By harnessing an ancient defense mechanism built into bacteria, CRISPR allows scientists to target, delete and replace specific genes. It has been used extensively in other organisms, but research in humans has been slow.

The Chinese experiments reported last year were largely unsuccessful. Few of the embryos in the experiment were successfully modified, and even fewer had the changes that scientists intended to make. None of the embryos were gestated, and the authors of the study readily admitted that their error rate was too high for use on viable embryos.

. . . Britain now has become the first country to approve the use of public funding for such research. In the United States, labs have to find private funding for any research that creates or destroys human embryos, and some lawmakers seek to ban it altogether. Even in China, where the first "successful" editing occurred, the guidelines are murky.

The University of Kent's Darren Griffin called the [HFEA] ruling "a triumph for common sense" in a statement, and Sarah Norcross, director of Progress Educational Trust, lauded the decision as "a victory for level-headed regulation over moral panic."

From "UK scientists given go-ahead to genetically modify human embryos" by Sheena McKenzie, for CNN 2/1/16

Scientists will be focusing on the first seven days of a fertilized egg's growth. In these early days, a fertilized egg evolves from a single cell to around 250 cells.

The research, which will be led by Dr. Kathy Niakan, will take place at the Francis Crick Institute in London and has been hailed as a "triumph for common sense" by leading figures of the British science community.

However, the research has also raised concerns that it could pave the way for "designer babies" -- going beyond health improvements and modifying everything from a child's eye color to intelligence.

From "British scientists granted permission to genetically modify human embryos" by Sarah Knapton, Science Editor, UK Telegraph 2/1/16

Currently around 50 per cent of fertilised eggs do not develop properly and experts believe that faulty genetic code could be responsible.

If scientists knew which genes were crucial for healthy cell division, then they could screen out embryos where their DNA was not working properly, potentially preventing miscarriages and aiding fertility.

The team at Francis Crick are already in talks with fertility clinics across the country to use their spare embryos.

Dr Calum MacKellar, Director of Research of the Scottish Council on Human Bioethics said: “Allowing the gene editing of embryos opens the road to genetically modifying all the descendants of a person as well as full blown eugenics which was condemned by all civilised societies after the Second World War.”

From "Britain grants first licence for genetic modification of embryos" posted at Medical Xpress 2/1/16

[Dr. Kathy] Niakan has said she is planning to modify the embryos using a technique known as CRISPR-Cas9, which allows scientists to insert, remove and correct DNA within a cell.

The embryos will not become children as they must be destroyed within 14 days and can only be used for basic research.

She plans to find the genes at play in the first few days of fertilisation when an embryo develops a coating of cells that later become the placenta.

The embryos to be used in the research are ones that would have been destroyed, donated by couples receiving In-Vitro Fertilisation (IVF) treatment who do not need them.

From "British researchers get green light to genetically modify human embryos" by Haroon Siddique, UK Guardian 2/1/16

Prof Robin Lovell-Badge, group leader at the Francis Crick Institute . . . said it would also provide invaluable information about the accuracy and efficiency of the technique, helping to inform the debate about whether genome editing could be used in future to correct faulty genes that cause devastating diseases.

That prospect remains a long way off but is already a subject of concern. There are also fears that changes to an embryo’s DNA could have unknown harmful consequences throughout a person’s body and be passed on down the generations.

Last year, leading UK funders called for a national debate on whether editing human embryos could ever be justified in the clinic. Some fear that a public backlash could derail less controversial uses of genome editing, which could lead to radical new treatments for disease.

From "Pro-life charity criticises decision to allow UK scientists to genetically modify human embryos" by Staff Reporter, Catholic Herald 2/1/16

After the announcement Anne Scanlan, the education director of Life, said . . . “[HFEA] has ignored the warnings of over a hundred scientists worldwide and given permission for a procedure, which could have damaging far-reaching implications for human beings. We do not know what long term side effects the tampering with some strands of DNA could have on other strands. However once genetic changes have been made they will be irreversible and handed down to future generations.”

Miss Scanlan added: “We are also concerned that such controversial intervention in the human germline opens up the very real possibility of eugenics where the existence of human beings becomes conditional on the possession of certain physical characteristics.

“Whilst we note the HFEA restriction on the implantation of genetically modified embryos, it is sending the wrong signals by allowing scientists the ability to develop and possibly perfect the technology here in the UK. To mitigate any advancement on the potentially dangerous work being undertaken by these British scientists, we believe that an international ban on human DNA editing is urgently needed to protect the future of the human species.”

Creators of Life Worshiped — Prizes to Scientists

Disappointed after decades of searching in vain for life beyond Earth, science journalists have turned their focus to proven success in creating life here on Earth through genetic manipulation known as CRISPR-Cas9.  Not only are Nobel prizes in the offing, but funding sources have opened up, including from billionaire Bill Gates.  Although scientists envision endless possibilities for the potential good, they equally fear the inevitable devastating evil uses of such breakthroughs.
"The gene drive immediately makes the organisms that carry it have the characteristic, and then secondly it causes them to have all their children have the same characteristic."
-- Ethan Bier, Biologist, University of California, San Diego

"If any group or country wanted to develop germ warfare agents, they could use techniques like this.  It would be quite straightforward to make new pathogens this way."

-- From "Gene editing: Research spurs debate over promise vs. ethics" Lauran Neergaard, Medical Writer, Associated Press 10/11/15

Should we change people’s genes in a way that passes traits to future generations? Beyond medicine, what about the environmental effects if, say, altered mosquitoes escape before we know how to use them?

“We need to try to get the balance right,” said University of California, Berkeley, biochemist Jennifer Doudna. She helped develop new gene-editing technology and hears from desperate families, but urges caution in how it’s eventually used in people.

Laboratories worldwide are embracing a technology to precisely edit genes inside living cells — turning them off or on, repairing or modifying them — like a biological version of cut-and-paste software. . . .

“It’s transforming almost every aspect of biology right now,” said National Institutes of Health genomics specialist Shawn Burgess.

From "Powerful 'Gene Drive' Can Quickly Change An Entire Species" by Rob Stein, WBEZ-NPR (National Public Radio) 11/5/15

[Biologist Ethan] Bier was stunned by what he saw. . . . His student, Valentino Gantz, had found a way to get brown fruit flies to produce blond-looking offspring most of the time.

Turning fruit flies from brown to yellow might not sound like a major achievement. But it was. It showed that scientists had a very fast and easy way to permanently change an entire species.

The drive is a sequence of DNA that can cause a mutation to be inherited by the offspring of an organism with nearly 100 percent efficiency, regardless of whether it's beneficial for that organism's survival.

By combining it with new genetic editing techniques, scientists are able to drive changes they make quickly through an entire species.

The technology Bill Gates is most excited about: Say hello to gene editing!

. . . CRISPR technology, which is changing how we think about genetics and health. CRISPR technology basically allows for gene editing — it’s like a scapel that can cut out harmful mutations and turn genes on and off. The potential applications range from fighting hereditary disease in people to boosting crop yields to engineering cows without horns, so as to obviate a painful dehorning procedure. The ethical implications have barely been sussed out.

From "Nobel speculation kicks into high gear" by Chris Cesare, Nature 9/24/15

Nobel prize season is approaching, and scientists and other pundits have begun the annual ritual of speculating — with varying degrees of seriousness — about who will win this year’s awards.

The annual predictions by Thomson Reuters, released this year on 24 September, name more women than ever before: four in total. Among the potential laureates for the chemistry prize are Emmanuelle Charpentier of the Helmholtz Centre for Infection Research in Braunschweig, Germany, and Jennifer Doudna of the University of California, Berkeley, who would share the prize for helping to create the CRISPR/Cas9 gene-editing technique.

If Doudna and Charpentier won, it would be just three years after they published their seminal paper.

From "The Gene Hackers" by Michael Specter, The New Yorker 11/9/15 (November 16, 2015 Issue)

CRISPR has two components. The first is essentially a cellular scalpel that cuts DNA. The other consists of RNA, the molecule most often used to transmit biological information throughout the genome. It serves as a guide, leading the scalpel on a search past thousands of genes until it finds and fixes itself to the precise string of nucleotides it needs to cut. . . .

With CRISPR, scientists can change, delete, and replace genes in any animal, including us. . . .

Inevitably, the technology will also permit scientists to correct genetic flaws in human embryos. Any such change, though, would infiltrate the entire genome and eventually be passed down to children, grandchildren, great-grandchildren, and every subsequent generation. That raises the possibility, more realistically than ever before, that scientists will be able to rewrite the fundamental code of life, with consequences for future generations that we may never be able to anticipate. Vague fears of a dystopian world, full of manufactured humans, long ago became a standard part of any debate about scientific progress. . . .

Developing any technology as complex and widely used as CRISPR invariably involves contributions from many scientists. Patent fights over claims of discovery and licensing rights are common. [Feng] Zhang, the Broad Institute, and M.I.T. are now embroiled in such a dispute with Jennifer Doudna and the University of California; she is a professor of chemistry and of molecular biology at Berkeley. By 2012, Doudna, along with Emmanuelle Charpentier, a medical microbiologist who studies pathogens at the Helmholtz Centre for Infection Research, in Germany, and their lab teams, demonstrated, for the first time, that CRISPR could edit purified DNA. Their paper was published that June. In January of 2013, though, Zhang and George Church, a professor of genetics at both Harvard Medical School and M.I.T., published the first studies demonstrating that CRISPR could be used to edit human cells. Today, patents are generally awarded to the first people to file—in this case, Doudna and Charpentier. But Zhang and the Broad argued that the earlier success with CRISPR had no bearing on whether the technique would work in the complex organisms that matter most to scientists looking for ways to treat and prevent diseases. . . .

CRISPR research is becoming big business: venture-capital firms are competing with one another to invest millions, and any patent holder would have the right to impose licensing fees. Whoever wins stands to make a fortune. Other achievements are also at stake, possibly including a Nobel Prize. . . .

From the moment that manipulating genes became possible, many people, including some of those involved in the experiments, were horrified by the idea of scientists in lab coats rearranging the basic elements of life. . . .

Normally, it takes years for genetic changes to spread through a population. That is because, during sexual reproduction, each of the two versions of any gene has only a fifty per cent chance of being inherited. But a “gene drive”—which is named for its ability to propel genes through populations over many generations—manages to override the traditional rules of genetics. A mutation made by CRISPR on one chromosome can copy itself in every generation, so that nearly all descendants would inherit the change. . . .

While CRISPR will clearly make it possible to alter our DNA, serious risks remain. Jennifer Doudna has been among the most vocal of those calling for caution on what she sees as the inevitable march toward editing human genes. “It’s going to happen,” she told me the first time we met, in her office at Berkeley. “As a research tool, CRISPR could hardly be more valuable—but we are far from the day when it should be used in a clinical setting.” . . .

Until April, the ethical debate over the uses of CRISPR technology in humans was largely theoretical. Then a group at Sun Yat-sen University, in southern China, attempted to repair, in eighty-six human embryos, the gene responsible for betathalassemia, a rare but often fatal blood disorder. If those disease genes, and genes that cause conditions like cystic fibrosis, could be modified successfully in a fertilized egg, the alteration could not only protect a single individual but eventually eliminate the malady from that person’s hereditary lineage. Given enough time, the changes would affect all of humanity. The response to the experiment was largely one of fear and outrage. The Times carried the story under the headline “Chinese Scientists Edit Genes of Human Embryos, Raising Concerns.” . . .

[Doudna] told me that she was constantly amazed by [CRISPR] potential, but when I asked if she had ever wondered whether the powerful new tool might do more harm than good she looked uncomfortable. “I lie in bed almost every night and ask myself that question,” she said. “When I’m ninety, will I look back and be glad about what we have accomplished with this technology? Or will I wish I’d never discovered how it works?”

Her eyes narrowed, and she lowered her voice almost to a whisper. “I have never said this in public, but it will show you where my psyche is,” she said. “I had a dream recently, and in my dream”—she mentioned the name of a leading scientific researcher—“had come to see me and said, ‘I have somebody very powerful with me who I want you to meet, and I want you to explain to him how this technology functions.’ So I said, Sure, who is it? It was Adolf Hitler. I was really horrified, but I went into a room and there was Hitler. He had a pig face and I could only see him from behind and he was taking notes and he said, ‘I want to understand the uses and implications of this amazing technology.’ I woke up in a cold sweat. And that dream has haunted me from that day. Because suppose somebody like Hitler had access to this—we can only imagine the kind of horrible uses he could put it to.”

Unborn Must Die so Others Can Live, Scientists Say

An international group of scientists, ethicists and policy experts claim it is "essential" that experimentation on human beings, using "genetic modified (GM) embryos," be legalized to cure diseases and improve IVF and human reproduction.  However, critics say that too little is understood about the process, and furthermore, it will eventually lead to "designer babies."
“Restricting research because of concerns that reproductive application is premature and unsafe will ensure that it remains forever premature and risky, for want of better knowledge.”

The Hinxton Group, which describes itself as an international consortium on stem cells and bioethics, also said in a statement released on Wednesday that the engineering of GM babies—a concept commonly called designer babies—could be "morally acceptable" in the future, although it said it was not in favour of the procedure at present.

Modern gene-editing tools such as CRISPR/Cas9—a technique which can reportedly edit the genomic sequence in a highly targeted way—are "not only very precise, but also easy, inexpensive, and, critically, very efficient," the group said.

Earlier this year, Chinese scientists reportedly edited the genomes of human embryos in what was described as "a world first" by the journal Nature.

However, Debra Mathews, assistant director of science programs at the Johns Hopkins Berman Institute of Bioethics and a member of the Hinxton Group, said, in the statement, that despite “controversy and deep moral disagreement” over the issue, the solution was “not to stop all discussion, debate and research, but rather to engage with the public, policymakers and the broader scientific community”.

A group of experts on Wednesday said that human embryo genetic modification should be allowed, as it will help in understanding early embryos’ biology. However they said they would not support the birth of genetically modified human babies, for the time being.

Professor Emmanuelle Charpentier is of opinion that the human germline should not be manipulated just with the objective of changing some of the genetic traits.

From "GM embryos 'essential', says report" by James Gallagher, Health editor, BBC News 9/10/15

A meeting of the influential Hinxton Group, in Manchester, acknowledged that the rate of progress meant there was a "pressure to make decisions" and argued embryo editing should be allowed.

In a statement, it said: "We believe that while this technology has tremendous value to basic research and enormous potential... it is not sufficiently developed to consider human genome editing for clinical reproductive purposes at this time."

This is in stark contrast to the US National Institutes of Health, which has already refused to fund any gene editing of embryos.

Its director, Dr Francis Collins, who was also a key player in the Human Genome Project, said: "The concept of altering the human germline [inherited DNA] in embryos for clinical purposes has been debated over many years from many different perspectives, and has been viewed almost universally as a line that should not be crossed."

From "Research on gene editing in embryos is justified, group says" by Gretchen Vogel, Science Magazine (American Association for the Advancement of Science) 9/10/15

At a meeting on 3 and 4 September, 22 Hinxton Group members from Canada, the United Kingdom, the United States, Italy, Germany, Mexico, Israel, and the Netherlands met to discuss the scientific and ethical issues surrounding the use of gene-editing techniques in human cells, especially embryos, stem cells, and cells that can give rise to sperm or eggs. They concluded in a consensus statement released today that any use of the technologies for reproduction is premature. But scientists will need to test them on human embryos in the lab to find out whether the techniques ever could be safe and effective enough to use, they say. Lab-based experiments can also help answer important questions about early human development and the development of sperm and eggs cells, says Robin Lovell-Badge, a developmental biologist at the Francis Crick Institute in London and a member of the Hinxton Group steering committee.

The statement urges scientists who want to use genome editing in human embryos to “consider carefully the category of embryo used.” Using embryos left over from in vitro fertilization treatments might not provide the best data, the statement says, since those embryos already contain multiple cells. The editing techniques would likely affect each cell differently, so that the resulting embryo would be a mosaic of cells with different genetic alterations. The statement concludes that certain experiments will require researchers to create new embryos specifically for research, a practice that is controversial and prohibited in some countries.

From "Scientists push for serious debates over 'essential' human embryo testing" posted at Irish Examiner 9/10/15

Genetic modification of human embryos has officially been deemed as “essential” and should be allowed so scientists can better understand basic biology, according to a report.

However, scientists can’t get too excited yet as the group added that the technology is not yet advanced enough to be used in the reproduction process, and there is still the ongoing issue that some find the concept of genetically modified babies “morally troubling”.

But the group warns it would be “dangerous” to prevent research in the area, and member and academic Sarah Chan said: “Genome editing technologies hold huge potential for advancing basic research and improving human health. The prospect that genome editing may one day be used to create genetically modified humans should not in itself be cause for concern, particularly where what is at stake is curing or preventing serious disease.

UPDATE 9/10/15: Unborn Must Die so Others Can Live, Scientists Say

-- From "American scientists are trying to genetically modify human eggs" by Steve Connor, Science editor, UK Independent 3/13/15

The research was carried out on ovary cells taken from a woman with inherited ovarian cancer to investigate the possibility of eventually using gene-editing to produce IVF embryos free of the familial disease. The results are yet to be published.

Editing the chromosomes of human eggs or sperm to create genetically modified IVF embryos is illegal in Britain and many other countries because of concerns about safety and the possibility of the technique being used to create genetically enhanced “designer babies”.

Several teams of researchers around the world are believed to be working on ways of modifying the chromosomes of human egg cells with a view to moving towards “germ-line” gene therapy, as the process is called. Germ-line refers to the “germ” cells – sperm and eggs – that pass on genes to future generations.

The work was carried out last year by Luhan Yang, a researcher working in the lab of the veteran Harvard geneticist George Church. But the study has not been published in a scientific journal and Dr Yang was unavailable for comment.

Professor Church emphasised that the work was purely experimental. . . .

From "Alarm over genetic editing of human embryos that opens door to designer babies and superhumans" by Jayalakshmi K, International Business Times  3/13/15

Amidst rumours that precise gene-editing techniques have been used to create designer human embryos, researchers have called for a moratorium on the use of the technology.

Geneticist Xingxu Huang of ShanghaiTech University in China has sought permission from his institution's ethics committee to genetically modify discarded human embryos.

Precise gene-editing techniques in recent years use enzymes called nucleases to snip DNA at specific points and then delete or rewrite the genetic information at those locations. Methods like the CRISPR are simple enough to be done in a fertility clinic.

Geneticist Dana Carroll of the University of Utah in Salt Lake City says, "Germline genome alterations are permanent and heritable, so very, very careful consideration needs to be taken in advance of such applications."

From "Scientists want experiments of DNA editing in human embryos to stop" by Ravi Mandalia, Techie News 3/14/15

Rumours about such experiments have been circulating the web for quite some time now and critics of the work say that such experiments could be used to try to alter the genetic quality of humans, a practice and belief known as eugenics.

Edward Lanphier, president and chief executive officer of California-based Sangamo BioSciences Inc, and senior author of the commentary published in the science journal Nature call for a self-imposed research moratorium as the work crosses an ethical line. “Humans are not rats or other (experimental) organisms, and this is not something we want to do,” Lanphier said in an interview with Reuters quotes Zee News. “The research should stop.”

According to Lanphier, who is also the chairman of the Alliance for Regenerative Medicine in Washington DC, “Such research could be exploited for non-therapeutic modifications” and a “public outcry about such an ethical breach could hinder a promising area of therapeutic development.”

Lanphier added that genome-editing can itself introduce DNA errors and “the precise effects of genetic modification to an embryo may be impossible to know until after birth. Even then, potential problems may not surface for years.”

From "Scientists sound alarm over DNA editing of human embryos" by David Cyranoski, Nature 3/12/15

Known as germline modification, edits to embryos, eggs or sperm are of particular concern because a person created using such cells would have had their genetic make-up changed without consent, and would permanently pass down that change to future generations.

Germline gene editing is already banned by law in many countries — a 2014 review by Tetsuya Ishii, a bioethicist at Hokkaido University in Sapporo, Japan, found that of 39 countries, 29 have laws or guidelines that ban the practice. But the development of precise gene-editing techniques in recent years has brought fresh urgency to the issue. These techniques use enzymes called nucleases to snip DNA at specific points and then delete or rewrite the genetic information at those locations. The methods are simple enough to be used in a fertility clinic, raising fears that they might be applied in humans before safety concerns have been addressed.

Ishii worries about countries such as the United States: there, germline editing is not banned but requires government approval, but such restrictions have a history of being circumvented, as in the case of unproven stem-cell treatments. He is also concerned about China, which prohibits gene-editing of embryos but does not strictly enforce similar rules, as shown by failed attempts to curb the use of ultrasound for sex selection and to stamp out unauthorized stem-cell clinics. China is also where gene-editing techniques in primates have developed fastest. “There are already a lot of dodgy fertility clinics around the world,” he says.

. . . At some point between now and July, the UK parliament is likely to vote on whether a new form of in vitro fertilization (IVF)—involving DNA from three parents—becomes legally available to couples. . . .

The procedure involves replacing mitochondrial DNA (mtDNA) to avoid destructive cell mutations. . . .

. . . the U.S. Food and Drug Administration will start reviewing the data in earnest in February.  Among the concerns on the table is whether the mtDNA donor mother could be considered a true “co-parent” of the child, and if so, can she claim parental rights?

Even though the donor would be contributing just 0.1 percent of the child’s total DNA (according to the New Scientist report), we don’t as yet have a DNA benchmark to judge the issue. Who is to say what percentage of a person’s DNA must come from another human to constitute biological parenthood?

From "Freeing human eggs of mutant mitochondria" by Alla Katsnelson, Nature 4/14/2010

Researchers have successfully transplanted the genetic material in the nucleus of a fertilized human egg into another fertilized egg, without carrying over mitochondria, the energy-producing structures of the cell. The technique could be used to prevent babies from inheriting diseases caused by mutations in the DNA of mitochondria, which are present in the cytoplasm of the egg.

The British team carrying out the study used fertilized eggs donated by couples undergoing fertility treatment, and which were unsuitable for in vitro fertilization (IVF). At this early stage the sperm and egg nuclei, which contain most of the parental genes, have not yet fused. The researchers removed these nuclei and transferred them into another fertilized egg cell which had had its own nuclei removed.

[Shoukhrat Mitalipov at Oregon Health & Science University in Portland said,] Using fertilized eggs may pose an ethical problem . . . as the transplantation procedure destroys the donor embryo.

This procedure, which involves removing the nucleus from one human egg whose cytoplasm contains defective mitochondria and placing it in an enucleated egg with healthy DNA for subsequent fertilisation, is also being debated in the UK.

The measure is strongly opposed by the Center for Genetics and Society, which is promoting an open letter to the FDA. It claims that mitochondrial transfer is unsafe, is effectively experimentation on unconsenting human subjects, and would only help a handful of women. Most importantly, it constitutes germline modification, a form of eugenics. This is a bright line which no country has ever stepped across.

The researchers at Oregon Health & Sciences University said they are not using the embryos to produce children, and it is not clear when or even if this technique will be put to use. But it has already stirred a debate over its risks and ethics in Britain, where scientists did similar work a few years ago.

The British government is asking for public comment on the technology before it decides whether to allow its use in the future. One concern it cites is whether such DNA alteration could be an early step down a slippery slope toward "designer babies" — ordering up, say, a petite, blue-eyed girl or tall, dark-haired boy.

Questions have also arisen about the safety of the technique, not only for the baby who results from the egg, but also for the child's descendants.

Laurie Zoloth, a bioethicist at Northwestern University in Evanston, Ill., said in an interview that safety problems might not show up for several generations. She said she hopes the United States will follow Britain's lead in having a wide-ranging discussion of the technology.

This technique was trialled in four monkeys in 2009. They all gave birth to healthy offspring which are still going strong.

Now, Shoukhrat Mitalipov of the Oregon National Primate Research Center in Beaverton, and his colleagues have fused human eggs using a similar technique. Mitalipov extracted the nucleus from 65 eggs and replaced each one with the nucleus from another donor egg.

The team then fertilised the eggs and let them grow into a ball of about 100 cells called a blastocyst. This takes about five or six days and is normally around the time that such a fertilised egg would become implanted into the womb. Of the 65 donated eggs that were fertilised, 48 per cent grew into healthy-looking blastocysts. Their development was similar to that of 33 unaltered fertilised eggs.

Just over half of the eggs in the study developed abnormally.

From "Scientists in Oregon Create Embryos With Three Genetic Parents" by Rebecca Taylor, LifeNews.com 10/25/12

Why would scientists want to engineer an embryo with the genetic material from three people? Because they say it will “prevent” the inheritance of mitochondrial disease. Not all of our DNA that we inherit is in the nuclei of the egg and sperm that join at fertilization. In the cytoplasm of our mother’s egg are mitochondria. Mitochondria have their own DNA called mtDNA. We inherit our mtDNA only from our mother because sperm’s mitochondria are dumped at conception. There are genetic mutations that cause very serious disease found in mtDNA and a woman with a such a mutation cannot help but pass this mutation on to her children.

Gay Procreation: Successful Offspring from Two Males

A scientific breakthrough could challenge one more argument in opposition to the Gay Agenda: Marriage is a design for procreation.

-- From "Mice created from two dads" by John Roach, contributing writer for msnbc.com 12/9/10

Reproductive scientists have used stem cell technology to create mice from two dads. The breakthrough could be a boon to efforts to save endangered species -- and the procedure could make it possible for same-sex couples to have their own genetic children.

The scientists, led by Richard Berhringer at the M.D. Anderson Cancer Center in Texas, describe the process in a study posted Wednesday in the journal Biology of Reproduction.

The study authors say their technique could be applied to animal breeding efforts, so that two males with desirable traits could be crossed without mixing in traits from females. "It is also possible that one male could produce both oocytes (eggs) and sperm for self-fertilization to generate male and female progeny," the team writes. This could help save an endangered species that no longer had females to mate with, for example.

In the future, scientists may be able to create human eggs from male iPS cells in vitro, allowing them to eliminate the need for the intermediate offspring, though a surrogate mother would still be needed to carry the two-father pregnancy to term.

From "Mice Are Created From Two Males" by Gautam Naik, Wall Street Journal 12/10/10

Researchers at University of Texas M.D. Anderson Cancer Center and elsewhere first engineered a female mouse whose eggs contained the DNA from a male. When the female was mated with another male, the offspring had genetic contributions entirely from two males. The study appears online in the peer-reviewed journal Biology of Reproduction.

New techniques are allowing scientists to tweak the biology of reproduction in unusual ways. In April, scientists at U.K.'s Newcastle University created embryos with DNA taken from a man and two women.

Trying this in humans is a much bigger challenge. When a human embryo inherits only one X chromosome (instead of one chromosome from each parent) it tends to die. Rarely, females are born this way, called Turner syndrome, and all are infertile. And scientists would also have to find a way to create eggs without creating human chimeras, which is ethically contentious.

God Replaced? Scientists Create Life

Synthetic life has been created in the laboratory in a feat of ingenuity that pushes the boundaries of humanity’s ability to manipulate the natural world.


UPDATE 5/27/10: Vatican weighs in with support and caution

-- From "A step to artificial life: Manmade DNA powers cell" by Lauran Neergaard, Associated Press 5/21/10

Scientists announced a bold step Thursday in the enduring quest to create artificial life. They've produced a living cell powered by manmade DNA. While such work can evoke images of Frankenstein-like scientific tinkering, it also is exciting hopes that it could eventually lead to new fuels, better ways to clean polluted water, faster vaccine production and more.

Is it really an artificial life form?

The inventors call it the world's first synthetic cell, although this initial step is more a re-creation of existing life — changing one simple type of bacterium into another — than a built-from-scratch kind.

Following the announcement, President Barack Obama directed the Presidential Commission for the Study of Bioethical Issues he established last fall to make its first order of business a study of the milestone.

"The commission should consider the potential medical, environmental, security and other benefits of this field of research, as well as any potential health, security or other risks," Obama wrote in a letter to the commission's chairwoman, Amy Gutmann, the president of the University of Pennsylvania.

Obama also asked that the commission develop recommendations about any actions the government should take "to ensure that America reaps the benefits of this developing field of science while identifying appropriate ethical boundaries and minimizing identified risks."

From "Scientists create artificial life in laboratory" by Mark Henderson, Science Editor, London Times 5/21/10

The synthetic bacterium, nicknamed Synthia, has been hailed as a step change in biological engineering, allowing the creation of organisms with specialised functions that could never have evolved in nature. The team at the J. Craig Venter Institute in Rockville, Maryland, is investigating how the technology could yield microbes that make vaccines, and algae that turn carbon dioxide into hydrocarbon biofuels.

Dr Venter, who has been working on synthetic life for a decade, told The Times: “It is our final triumph. This is the first synthetic cell. It’s the first time we have started with information in a computer, used four bottles of chemicals to write up a million letters of DNA software, and actually got it to boot up in a living organism.

“Though this is a baby step, it enables a change in philosophy, a change in thinking, a change in the tools we have. This cell we’ve made is not a miracle cell that’s useful for anything, it is a proof of concept. But the proof of concept was key, otherwise it is just speculation and science fiction. This takes us across that border, into a new world.”

Julian Savulescu, Professor of Practical Ethics at the University of Oxford, said: “Venter is creaking open the most profound door in humanity’s history, potentially peeking into its destiny. He is going towards the role of a god: creating artificial life that could never have existed naturally. The potential is in the far future, but real and significant. But the risks are also unparalleled.”

The technique is controversial . . . because the children it creates would inherit genetic material from three parents. The mother and father would contribute most of their child’s DNA but a small amount would come from a second woman donating healthy mitochondria.

Such children would be the first produced by germline genetic engineering, in which genes introduced by artificial means would be passed to successive generations.

Although more than 99 per cent of a cell’s DNA is carried in the nucleus, a small amount resides in the mitochondria — tiny energy-producing structures inherited from the mother — and it is mutations in this mitochondrial DNA that can cause disease.

UK: Parliament Votes to Allow Creation of Human Animal Hybrids

Exaggerated hope for cures leads Brits to cross a terrible line...

From "MPs back creation of human-animal embryos" by Mark Henderson and Francis Elliot, posted 5/20/08 at timesonline.co

British scientists will be allowed to research devastating diseases such as Alzheimer’s and Parkinson’s using human-animal embryos, after the House of Commons rejected a ban yesterday.

An amendment to the Human Fertilisation and Embryology Bill that would have outlawed the creation of “human admixed embryos” for medical research was defeated in a free vote by a majority of 160, preserving what Gordon Brown regarded as a central element of the legislation.

...A second amendment, which would have banned the creation of “true hybrids” made by fertilising an animal egg with human sperm, or vice-versa, was...defeated yesterday by a majority of 63. Another free vote last night was expected to approve the use of embryo-screening to create “saviour siblings” suitable to donate umbilical cord blood to sick children.

Edward Leigh, Conservative MP for Gainsborough, moving the amendment to ban all admixed embryos, said that mingling animal and human DNA crossed an “ultimate boundary”. He said that exaggerated claims were giving patients false hope and that the dangers of the research were unknown. “In many ways we are like children playing with landmines without any concept of the dangers of the technology we are handling,” he said.

Part-Human Embryos are a Chilling Step Closer as Watchdog Gives Go-Ahead for Hybrid 'Chimeras'

From "Part-human embryos are a chilling step closer as watchdog gives go-ahead for hybrid 'chimeras'" by Fiona McRae, posted 9/5/07 at DailyMail

The creation of part-human, part-animal embryos looks set to be approved by the fertility regulator tomorrow.

These "hybrid" embryos would be used for research into incurable diseases such as Alzheimer's.

The news follows a surprise Government decision not to ban the controversial research.

A shortage of human eggs has led two groups of scientists to appeal to the Human Fertilisation and Embryology Authority for permission to make hybrid embryos from human skin cells and animal eggs.

Cows' eggs are most likely to be used, because they are in plentiful supply.

Scientists say the creation of hybrid embryos has the potential to revolutionise the treatment of debilitating diseases which affect millions.

But opponents believe mixing of human and animal genetic material defies nature.

They are also unhappy about the destruction of embryos that such research inevitably entails.

The scientists' hopes to use hybrids were initially jeopardised by a proposal to outlaw such research under a shake-up of outdated fertility laws.

But in May, Labour ministers dramatically changed their minds.

However, only scientists who are researching serious diseases - and are licensed by the HFEA - will be allowed to carry out such procedures.

While the fertility watchdog has yet to rule on the issue, its ethical and scientific experts are in favour of the creation of hybrids.

The watchdog looks suspiciously like a fox...

Disturbing Trend: Childrened Designed to be Disabled

From "Disturbing trend: Designer children designed to be disabled" by Joseph D'Agostino, posted 4/2/07, at Lifesite.net

For some years now, some deaf parents have refused to allow their deaf children to receive cochlear implants that would enable them to hear. The devices must often be implanted when children are very young in order to work, so such parents condemn their children to a lifetime of deafness when they could have been able to hear.

Some dwarf couples are even using in-vitro fertilization to create embryos in the lab, then killing the normal ones and implanting the ones with the dwarfness gene to ensure having a dwarf child .

The standard Marxist-Frankfurt School arguments are used to justify such acts by Deaf Life magazine and other radical organizations representing some disabled people. They argue that deaf folks, dwarfs, and others aren’t disabled at all, just different. Deaf Life types complain of an “oralist” culture that discriminates against deaf people who use sign language. “Oralism” oppresses the deaf, you see, just as racism, sexism, heterosexism, and other isms ad nauseam oppress others.

In a Jan. 21, 2007 story, the Associated Press reported that, of American clinics it surveyed that perform embryo screening, 3% admit to screening in favor of disabilities. This story contains perhaps the most revealing statement on the question. It was uttered by a dwarf woman angered that anyone would dare suggest that deliberating inflicting permanent suffering on children is bad:

“Cara Reynolds of Collingswood, N.J., who considered embryo screening but now plans to adopt a dwarf baby, is outraged by the criticism. ‘You cannot tell me that I cannot have a child who's going to look like me,’ Reynolds said. ‘It's just unbelievably presumptuous and they're playing God.’”

Funny to think that it’s playing God to say it’s wrong to use high-tech techniques to choose certain qualities in children rather than letting nature take her course. Isn’t intervening to choose a major genetic
quality in your child much more like playing God?

First abortion, then fetal and embryonic tissue experimentation, and on the anti-child bandwagon goes. Some kill children because they have disabilities, others choose to inflict suffering that only God could
possibly have a right to allow. What hate there is in the world.
