“I think the paper itself actually provides all of the data that we kind of pointed to,” he says.But George Church, a geneticist at Harvard Medical School, disagrees that the technology is that immature.There are 22 references cited in this article, which can be found at the bottom of the page.

Furthermore, the technique failed entirely in most of the embryos they experimented on.

Edward Lanphier, president of Sangamo Bio Sciences in Richmond, California, who co-authored a 19 March Comment piece in Nature calling for a halt on such research, says that these technical challenges point to the immaturity of the field and thus support arguments for a moratorium on all human germline-modification research.Others say that modifying germline cells could be acceptable if it is solely for the purposes of research.George Daley, a stem-cell biologist at Harvard Medical School in Boston, Massachusetts, points out that using CRISPR/Cas9 and other gene-editing tools in human embryos, eggs and sperm could answer plenty of basic scientific questions that have nothing to do with clinical applications. Modifying human embryos is legal in China and in many US states, although the US National Institutes of Health (NIH) forbids the use of federal funds for such research.To justify banning gene editing for safety reasons, he says, one would not only need to have a reason to think that it will be harmful, but also that this harm would be worse than the genetic disease itself. “People with genetic diseases are going to go on reproducing.” He likens the concerns to avoiding a surgery because of fear of complications.Hank Greely, a bioethicist at Stanford University in California, notes that there will be different degrees of safety concerns.They published a paperwas reported by Nature's news team on 22 April, confirming rumours that had been circulating for months that scientists were applying such gene-editing techniques to human embryos.In March, the rumours prompted calls for a moratorium on such research: work in human embryos is contentious because, in principle, any genetic changes will be passed to future generations, a scenario known as germline modification.Asked whether Huang’s study would have been allowed under its rules, the NIH says that it “would likely conclude it could not fund such research” and is watching the technology to see whether its rules need to be modified.Another point of contention is that Huang’s and colleagues' gene editing had a low success rate.Some feel that Huang’s group has already crossed an ethical line.“No researcher has the moral warrant to flout the globally widespread policy agreement against altering the human germline,” Marcy Darnovsky, executive director of the non-profit Centre for Genetics and Society in Berkeley, California, wrote in a statement.
