The birth-related stem cell clinic industry is a serious problem for patients, the stem cell field, and the FDA as the clinics sell more and more of what I think of as “zombie” injections. One of the biggest changes in the last 2 years in the unproven stem cell clinic arena was predicted by the data that Leigh Turner and I published in one of our collaborative papers in which we saw an upward slope in the number of businesses selling amniotic or other …Read More

I recently conducted an interview with Dr. Joanne Kurtzberg of Duke. You can see Part 1 of the interview here. Today in Part 2, I asked Dr. Kurtzberg some broader questions about the stem cell field. 1.

Perhaps because of my blog, I get contacted by parents of pediatric patients lately at least once a week about possible stem cell treatments for CP, autism, and …Read More
