My colleague Leigh Turner and I today published a new paper in Cell Stem Cell documenting for the first time the American stem cell clinic arena in a comprehensive way, which we found as of February has a remarkable 570 clinic locations via 351 businesses. These numbers are way beyond the predictions of most researchers and policy makers for stem cell clinics in the U.S., and point to a burgeoning, huge industry from coast to coast (see map below of clinic locations that we …Read More

An elderly woman in Australia reportedly died shortly after receiving a fat stem cell transplant. Sheila Drysdale passed away hours after getting an adipose stem cell treatment a few days before Christmas in 2013. That death is now being investigated by the coroner there. Not only is this death in Sydney distressing in it of itself, but also it raises broader safety concerns across the globe including here in the U.S. because fat stem cell treatments of this kind are so widely administered. Most …Read More

I blogged recently about how Sacramento has a new stem cell clinic using amniotic stem cells called Nervana Stem Cell Center.

The FDA is still in the process of getting public comment and finalizing draft guidelines related to stem cell clinical products including fat stem cells aka adipose stem cells and stromal vascular fraction or SVF. Even so, the FDA just …Read More

Is it the beginning of the end for dubious American clinics that sell transplants of unproven and non-FDA approved fat stem cell injections? As the year of 2014 was winding down, the FDA issued two key new draft guidances (see here and here) that could prove to be crash diets for these burgeoning fat stem cell clinics. (Update: As of 2020, the FDA has now clearly defined fat stem cells as drug products and filed suit against two firms marketing unapproved fat stem cells.) These new FDA guidances indicate …Read More

I recently interviewed Drs. Elliot Lander and Mark Berman of the Cell Surgical Network, an affiliated chain of clinics selling stem cell interventions for more than a dozen medical conditions. You can read Part 1 here and Part 2 here of the interview where we cover 10 important questions. Today is Part 3, where I explain why their answers deeply trouble me. First, let me answer a question myself: why interview the leaders of the Cell Surgical Network, especially if I felt going into it that I would …Read More
