The biggest debate today in the stem cell world is over how much regulation is needed for new, investigational stem cell therapies that are not as yet approved. Sometimes it feels very lonely being out there publicly advocating for appropriately thorough regulation of stem cell therapies and at times I get a lot of heat for that, especially from stem cell clinics. For instance, I am publicly opposed to the REGROW Act, a piece of legislation that would dangerously weaken oversight of experimental stem cell therapies. …Read More

Last week was a big one for the life sciences in that we saw the milestone of the first ever published paper reporting human embryo genetic modification (see here and here). It was one of those situations where we knew it was coming, but it was still a jolt. Not surprisingly this event sparked intense discussion and even some arguments. Below are 4 areas of contention at this moment and some additional thoughts on them. I value diverse views so please weight in with comments. A big deal …Read More

CRISPR Cas9 gene editing technology is a game changer on many levels both inside and soon outside the lab. There is a growing sense of urgency amongst biomedical scientists to take a proactive approach to current and future use of CRISPR gene editing technology in human germ cells and embryos. These concerns have been heightened by rumors of multiple papers currently in various stages of peer review that will reportedly describe CRISPR-mediated gene editing of human embryos. A number of scientists and scientific organizations have recently come …Read More

The International Society for Stem Cell Research (ISSCR) just now released a new policy statement on human germline gene editing. The statement calls for a ban on clinical application of human germline gene editing technology. Here is the brief summary statement at the beginning: The International Society for Stem Cell Research calls for a moratorium on attempts at clinical application of nuclear genome editing of the human germ line to enable more extensive scientific analysis of the potential risks of genome editing and broader public …Read More
