The goal of today’s post is to fact-check claims about supposed stem cell stroke therapies and educate readers on where clinical research stands. There is some real hope here in the long run, but things have been greatly exaggerated at times. Some clinics are …

I hadn’t remembered the history of the philosopher’s stone until reading a new review article about stem cells and aging. Here’s the article. Is the philosopher’s stone to rejuvenate blood stem cells an epigenetic regulator? Nature Aging. This preview kind of piece discusses how inhibiting a specific factor called PHF6 can “rejuvenate” HSCs in mice. …

FDA stem cell policy flow chart.

The big news of the week was the big FDA stem cell in court by Judge Jesus Bernal here in California, who ruled in favor of a chain of stem cell clinics called Cell Surgical Network. The FDA had been seeking an injunction against the clinics. I believe the ruling was founded in part on …

Did COVID derail FDA stem cell clinic plan?

Mark Raza FDA stem cell clinic plan

The FDA stem cell clinic problem just continues to grow, while the agency has been oddly quiet in this space for more than a year. It’s been a major disappointment, particularly as in recent years FDA leadership had implied that bold action was coming. Their own words spiked expectations that the agency would tackle unproven …

Fact-checking troubling R3 Stem Cell clinic chain

Map of R3 stem cell clinic locations

I’ve had concerns about an American unproven clinic firm called R3 Stem Cell for many years. They sell unproven stem cell-related “treatments” via dozens of affiliated locations. I put quotes around treatments because in my view there is no good evidence here for claims of treating numerous serious illnesses. The goal of today’s post is …

VSELs, vsel ratajczak paper issues

A few people in the stem cell field keep arguing that adult pluripotent stem cells exist, including so-called “very small embryonic-like stem cells” or VSEL stem cells. These days the supposed cells are called VSELs or V-cells too. Only a handful of researchers have ever been able to report finding and studying these cells. Others …

One size doesn’t fit all? FDA may soften some cell therapy regs

dr. peter marks fda, cell therapy

The Pink Sheet just broke the story that the FDA may change up its oversight of the cell therapy space. This possible shift could drop the oversight bar somewhat for certain products. Most likely it’d be those with lower anticipated risks. The Pink Sheet piece by Sue Sutter is titled US FDA To Explore New Regulatory Pathways …
