Retraction Watch has been a great resource for those of us who have been following research misconduct. They widely cover and conduct research on retractions, corrections, and other developments in this space. Unfortunately, there’s been plenty to write about even just within the stem cell and cell therapy arena, which is my primary interest. Think …
I’ve been more interested in histones and their modifications versus DNA methylation when it comes to epigenetics and chromatin. In part this has just been because I have studied histones so much more. For example, we have been knocking out the two histone variant H3.3 genes, H3f3a and H3f3b, now for a decade. My lab also …

It’s a big challenge to get a cell therapy approved by the FDA and if you look at my list of FDA-approved stem cell therapies, it’s not as long as we might hope. FDA OK on cell therapy from Gamida Cell For this reason, it was excellent news to see that the FDA approved a …

It’s been almost seventeen years that I’ve been a professor here at UC Davis Medical School. It feels like home. I enjoy teaching our first-year medical students each year. Some end up doing research in my lab. Our school recently got a nice write-up over at STAT News by Usha Lee McFarling on the diversity …

Someday could human brain organoids get to the point of having organized human-like thoughts? Even consciousness? The more time passes, the less likely I think this is. It’s not impossible, but brain organoids have big limitations in that regard. To be clear, I don’t mean brain organoids having some vaguely human brain-like electrical activity. Even monolayers of …

Imagine writing or editing an article for the WaPo about risky, unproven medical interventions for COVID that desperate patients might consider. Then you link directly to the websites selling this stuff in your article. What the heck? WaPo links to risky long COVID “treatments” By linking, you not only are driving customers to these firms, …

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 …

As I’ve mentioned recently, it’s my busy time for medical school teaching and not long ago we did a GI lab that included one of my favorite structures in the course: taste buds. Taste buds The medical students seem fascinated with taste buds too. I can tell as their professor when something is particularly interesting …

Some people consider the brain to be equivalent to a living computer and in that sense it’s too bad that computers don’t have the equal of neural stem cells to help them fix themselves. Is the internet one big neural network-like web? There was a quake in the stem cell internet as CIRM’s main website …

If there’s one area of biologics where the FDA has been consistently busy lately it’s the perinatal cell therapy space. The agency has made it clear in the last year that allogeneic birth-related cell products are often drugs requiring premarket approval. This has mainly manifested at a practical enforcement level. We’ve seen actions taken in …
