Last week one of the most popular stories was about a preprint from a mammoth de-extinction research group led by George Church having made elephant stem cells. I finally got a chance to look carefully at their preprint. Elephant stem cells preprint and mammoth de-extinction The elephant stem cells preprint has solid data. It looks like […]

Anti-aging might already be the big regenerative medicine story of 2024 and it’s only early March. Anti-aging hype going to the dogs? One of my 20 stem cell and regenerative medicine predictions for 2024 was that longevity would continue to make big news including in some not-so-great ways. In just over two months there has
Are small clusters of cells that make up 5-day-old human embryos equivalent to children? Biologically and in terms of just common sense, the answer is “no.” These tiny spheres have around 100 cells and no organs. Actual people have many trillions of cells, brains, and other organs. Alabama law on embryos may block IVF About
There’s a fascinating type of olfactory cell. These so-called tuft cells have unusual characteristics, especially for nose cells. I had never heard of them before until reading a new article. The inside of the nose may not seem like a very attractive place but there are cool “nose stem cells” in there. More broadly, there

Exactly ten years ago today, on January 29, 2014, I wrote about two new Nature papers on so-called STAP cells. The papers claimed that stress alone could convert regular non-stem cells into some of the most powerful stem cells. More specifically, the authors claimed to make pluripotent stem cells similar to iPS cells this way.
Years ago I wrote about how I wished humans could form a blastema, which is a special area of regeneration near an injury that drives tissue replacement. For example, when a lizard loses its tail to a pursuing bobcat, if it can regrow a new one that process will depend on a blastema. The same goes

Every year I make stem cell and regenerative medicine predictions. Looking at my predictions for 2023, they reflect a wild year but in many ways a good one overall. Below I have graded my 2023 predictions. Overall, my crystal ball gave solid results. Some of the predictions have been condensed to keep things concise, but you

What is a woolly dog? Is it somehow related to the Woolly Mammoth? Before we get into that and the rest of my recommended reads, note that I’m finalizing my list of contenders for this year’s The Screamers Science Hype Awards. Last year The BBC won The Screamers for an article “Baby’s life ‘probably saved’

The big news broke Friday that the FDA approved two new gene therapies for sickle cell disease. While the approvals were expected and the actual use of these treatments will be complex on several levels, this is a historic development. 2 FDA-approved gene therapies for sickle cell Friday’s news follows on recent UK approval for
For about as long as I’ve been writing The Niche, people have been asking about stem cells for MS. There’s a huge need for new therapies. While a chemo-based approach with autologous hematopoietic stem cell transplantation (HSCT) looks to work for certain cases of multiple sclerosis (although not yet approved in the US), other cell
