Two prominent scientists, Robin Lovell-Badge and George Daley, have been amongst the most outspoken proponents of leaving the door open to heritable human genetic modification via CRISPR. While they each have articulated their reasons in somewhat different ways at times, their core reasons arguing in favor of future heritable CRISPR appear largely the same. In this post I tackle each of these arguments in favor of leaving the door open to “CRISPR babies” with science-based counterarguments. I also raise larger risks to going down …Read More

What happens when one of the most exciting stem cell biotechs ViaCyte teams up with a firm like CRISPR Therapeutics to use a combination of gene editing and cell therapy? Hopefully a synergistic partnership emerges that in this case can develop an effective stem cell-based therapy for diabetes. You can see a press release on the news. (Update, see my new interview after the news broke with ViaCyte CEO Paul Laikind) ViaCyte has been a frequent subject of posts on The Niche related to …Read More

Heritable CRISPR to be tried in humans sooner or later…or never? Will someone somewhere in the world try to use CRISPR gene editing or related technology to introduce heritable genetic changes into actual human beings in the next decade? I’m not talking about gene editing viable human embryos just for research which is already ongoing, but rather CRISPR’ing human embryos to then use to try to make babies who grow up to be adult humans with a specific genetic change. How likely is this? Take …Read More

“If I’m going to the trouble of cloning myself, I want the clone to be a copy of me!” I’m imagining what someone might say if they were told that their expensive and ethically dubious personal cloning efforts produced a clone that was somebody else instead of them. Even if the clone was very similar to the clonee, perhaps like a sibling who was nearly but not quite an identical twin, the clonee might be totally PO’d. When I think about “human “cloning” I …Read More
