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. Then he was asked again to help in early 2021. This was shortly before he resigned at the start of the Biden Administration. The push came from …

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 …

Regenerative medicine reads: retraction, FDA warning, CAR-T, ARM CEO

Timothy D. Hunt, new CEO of ARM, Alliance for Regenerative Medicine

I’ve tried to find some time to do some stem cell and other regenerative medicine reading too, but it’s been a busy week of teaching for me as a professor in our new academic year for the UC Davis School of Medicine. I help to teach the Histology part of the first-year curriculum. It’s an …

Weekly reads: NIH grants, side effect of darker hair, FDA warning, CRISPR

Grant writers handbook, grants cartoon

The last six months I’ve been spending even more time than usual writing NIH grants (and a few others). The last two weeks have been especially busy on this front as I am getting an R01 renewal out the door. My paper reading lately has been mostly related to the grant writing I’m doing. Still, …

Weekly reads: teratoma in iPSC trial, Piero Anversa & friends, Athersys, China Initiative

Dr-Piero-Anversa

It’s been mostly a downbeat week on the stem cell news front including a deep revisit by Reuters to the Piero Anversa case that has new revelations. It’s ugly stuff involving other folks too. We’ll start on the iPS cell front, where a trial participant had a teratoma. I’ve had a long-standing interest in the …

NIH R01 grant trends

Great ideas and talented scientists are not enough as biomedical research needs funding and here in the U.S. that means having R01 grant success. The trends since 1995 are slowly heading the wrong way. The average age of getting your first R01 grant keeps getting older. There is also still a bit of a possible …

Weekly reads: New FDA guidance, brains, MSCs, senescence

human mouse marmoset brain

This week marked the release of new draft FDA guidance on cell and gene therapies. Is the FDA kind of like the guidance counselor at school or more like the principal? It probably depends on many factors. I also find it funny how pretty much everyone in academia and biotech industry works to be compliant …

Human cloning is more likely now but would you take the big risks?

human cloning

I’ve been following the research related to human cloning now for more than a decade. Is human cloning more possible at this point? How do we even define such cloning? Did you know there are two types? The goal of this post is to educate you and in the process answer such questions. What’s in …
