Stem cell research.
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 […]

Remember Paolo Macchiarini, the famous-turned-infamous so-called “stem cell surgeon” who ended up in legal trouble and with trial participants who died? Before we get into this we have a new feature for our weekly reads, which is the stem cell and regenerative medicine tweet of the week. See that at the bottom of the post.

As we think about how much of a role belief should play in the hard sciences such as cell biology, a supposed cell type called VSEL or very-small embryonic stem cell-like cells comes to mind. For these guys it seems to me that the ratio of data to belief isn’t great. VSELs have nine lives. I

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

What if there was a likable person test that we could take to see how other people really view us scientists? How would that work? It turns out that a sense of likability might be more influential in academia than some of us might think, but it’s often problematic too. This came to mind because

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

Occasionally when I write a post there is an angry reaction to it in the blog comments, which was the case for my recent fact-check of the LifeWave X39 patches. As you can see in that post, I didn’t find convincing data to either back up the claimed stem cell connection. In my opinion, there

I’m sure many of you remember He Jiankui, the guy who made CRISPR babies. He ended up serving three years in jail in China. He seems to be trying for something of a comeback since his release. Were He Jiankui invitations a mistake? Some prestigious places have even invited him to give talks, which seemed

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes

Does Medicare cover stem cell therapy? Readers of The Niche have regularly asked this question. They’re curious about insurance coverage too. The answer is “no” in almost every case, with some notable exceptions I’ll get to at the end of the post. Still, clinics appear to have already been charging Medicare for what collectively adds
