FDA leader Stephen Hahn was pressured to aid Texas firm Direct Biologics

Former FDA Commissioner Stephen Hahn.

An FDA FOIA dump of text messages of former Commissioner Stephen Hahn suggests that a Texas regenerative firm called Direct Biologics benefited from political pressure on him in mid-2020.

Fact-checking exosome therapy: costs, risks, & lack of data

model of an exosome, exosome therapy

Exosome therapy is a still-experimental cell therapy approach aimed at treating specific diseases using secretions from cells. It’s novel since most attention on cell therapies has been given to using the actual cells themselves. In addition, this approach is a newer idea than using cells as the drug to treat diseases. Interestingly, the term “cell

Review of troubling R3 Stem Cell clinic chain

R3 stem cell

I’ve had concerns about an American unproven clinic firm called R3 Stem Cell for many years. They sell stem cell-related “treatments” via dozens of affiliated locations. I put quotes around treatments for a reason. In my view as a stem cell biologist, there is no good evidence here for claims of treating numerous serious illnesses.

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

Turner pub charts runaway stem cell clinic industry; FDA needs to think big now

U.S. Stem cell clinics map 2021.

Leigh Turner’s new Cell Stem Cell paper on the unproven stem cell clinic industry following up on our collaborative work together in 2015-2016 is great work but very discouraging. He found more than 2,700 clinics run by more than 1,000 firms in the U.S. This is several-fold growth since 2016. I’m very glad that Leigh has continued this line of
