Let’s start this week’s digest with a discussion of clonal expansion and mutations during cell and gene therapy development. Here’s the article that brought this to mind. Sickle cell gene therapy process may cause cancer-linked mutations in blood stem cells, Fierce Biotech. Clonal expansion This is a story about a non-CRISPR gene therapy using a […]
Some folks can view data from early, small clinical trials too skeptically or overly enthusiastically, and maybe that’s going on with some preliminary results from Verve Therapeutics. Good news? Bad news? I’m going to start with two articles about the same news that have very different vibes. What do I think? On the whole, I

For me, this was another week of heavy grant writing but also taking on Google again. How? Over how badly its search engine often performs on stem cell queries. I have a new piece at MedPage Today. It’s focused on the problem of Google Search promoting unproven stem cell clinic websites. Google still prefers stem

What’s more important than Woolly Mammoth de-extinction research in the stem cell arena? Only maybe a 10,000 other things. Still, the mammoth de-extinction efforts capture people’s attention much more than the average research story. Mammoth De-extinction update Is de-extinction only a pipette dream? This startup has a big, expensive plan to find out, Popular Science.
We all know people who seem far younger than their age, which feeds into the idea of biological age. It’s often in the news these days and all over social media. Some people who are fighting high-profile battles with aging are also doing something I call “health flexing.” I also called these folks by another

Neil Riordan may be most well-known for running the Panama stem cell clinic called simply enough the Stem Cell Institute, but he also has a U.S. firm Signature Biologics. The Panama clinic sells unproven umbilical cord cells grown in a lab for a host of medical conditions. I’ve had many concerns about it over the

It feels like we are marching towards a future in which key aspects of human reproduction, including the use of artificial wombs, could be substantially different than for most of history. The FDA is considering allowing a clinical trial for use of artificial wombs in people. Human trials of artificial wombs could start soon. Here’s

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

I’ve been thinking more about the steady stream of epigenetic clock research out there. How convincing is the research on such clocks? Do they tightly relate to human biological age? The related notion of turning back such hypothetical clocks to reverse aging is exciting but controversial. It doesn’t help that some are hyping all of

A days ago the news came about Mesoblast not getting FDA approval for its MSC product for GvHD. The MSC area has had a rough few years with various clinical trials including for COVID. The “stem cells for heart disease” arena has also had a tough time. Here’s more news along these lines: BioCardia pauses enrollment in PhIII trial
