What happens following pluripotent stem cell transplants into the brain? Are human IPS and ES cells going to function similarly in this context? We recently published a new translational paper on the behavior of human pluripotent stem cells when transplanted into the adult mouse brain in collaboration with my great UC Davis colleague, Dr. Veronica Martinez-Cerdeno. Martinez-Cerdeno V, Barrilleaux B, McDonough A, Ariza J, Yuen B, Somanath P, Le C, Steward C, Horton K, Knoepfler P. Behavior of xeno-transplanted undifferentiated human induced pluripotent stem cells is …Read More

There is a scientist’s dilemma: should you speak out on important, sometimes controversial issues in science, where you not only can potentially have positive impact, but also risk being attacked for it? Or do you remain silent? I’ve now been blogging for more than 7 years. I’ve battled the often exploitive for-profit stem cell clinics for years. But it goes beyond that. I’ve also worked against hype including sometimes that in the academic arena. For instance, in early 2015 I posted a probing review …Read More

Imagine an old man and a teenager sitting side by side, with blood flowing from the kid to the oldster in a stab at anti-aging. Sort of like a one-way fountain of youth via blood flow…Sci-fi?

A self-described ‘clinical trial’ of a sort by a company called Ambrosia essentially lets you buy an infusion of a younger person’s blood in an attempt at anti-aging for $8,000. Interested? Reportedly tech guru Peter Thiel is: “I’m not convinced yet …Read More

By Anna Everette “In our society, we have an addiction to vertical genetic transmission. It’s called sex and having a child who looks like you”. This was perhaps the most memorable quote from the event’s keynote speaker, Greg Simon, Director of the Biden Cancer Initiative. It also happens to highlight the most compelling reason to pursue this exciting technology. CRISPRcon took place on August 16-17 at the UC Berkeley and was meant to encourage communication about the range of ethical and social implications surrounding …Read More

Getting a stem cell shot or injection is completely 100% safe, right? An NFL star recently found out just how wrong that stem cell clinic mantra turned out to be. Jordan Reed, tight end for the Washington Redskins, has had issues with his big toe. He apparently thought that a stem cell injection there would be the ticket to a speedier recovery to get back on the field, but according to ESPN and Richmond Times Dispatch, this “shot in the arm” via the shot in …Read More
