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 …

Early during my postdoc I was primarily interested in the role of Myc genes both in cancer and in stem cells, work that later included embryonic stem cells. These cells are often called ES cells. At first I first started studying N-Myc in neural stem cells using a conditional knockout approach. However, soon after I was …

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 …

The Bay Area biotech Conception Bio has an intriguing name. What does “conception” mean here? Scientists can make many things from stem cells. For example, lately I’ve written a lot about stem cell-based human embryo models. Another intriguing area is called in vitro gametogenesis or IVG, where Conception Bio is a leader. IVG means making …

Imagine regularly having someone rub your face all over with the equivalent of a small roller covered with spikes and doused with either your blood or someone else’s and you have what’s called vampire facials. There’s more news that this is a very bad idea. Vampire facials linked to more HIV cases “Vampire facials” promoted …

Where do things stand with the investigative approach of stem cells for diabetes? 33% of Type 1 Diabetes Patients Insulin-Free With Stem Cells, Medscape. Not the best headline given the few number of participants here. If your study has only two subjects and one responds, someone is going to say, “50% of people had a …

There is still plenty of reason to worry about unproven stem cells being marketed in the U.S. and elsewhere around the world. I’ll start with a new item here in the U.S. on a firm called MD Stem Cells and end with a newly published paper about how things are going in Poland on this …

Researchers have been making stem cell-based embryo models for years now and a few folks have taken to calling these “stembryos.” Other names like gastruloids and blastoids are sometimes used too. “Embryo models” might be the simplest and best name. The embryo model research has advanced relatively quickly from very basic, not very organized structures …
