Key Mayo Clinic stem cell webpage is overexuberant & outdated

/ / 2 Comments
The Mayo Clinic.

The Mayo Clinic does some great research on stem cells and regenerative medicine. However, at times I’ve felt that a few Mayo researchers are overexuberant. This mainly relates to certain not-yet-proven stem cell and related offerings. Fitting with that perception, the Mayo website also has some inaccurate stem cell content that leans toward overstating things. […]

elephant stem cells

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

Multipotent & totipotent vs pluripotent stem cells, very early human embryos totipotent stem cells

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

Olfactory epithelium, Olfactory histology

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

Perspectives 10 years after STAP cells: the culture of science, misconduct, & hopes for progress

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.

Sholto David, stem cell, cancer retractions

It’s another one of those ‘double-grant’ weekends of grant writing (on brain cancer) and reviewing, but I’m still trying to find a bit of time for some other reading. There was some important news this week including a big mess of problematic papers at Dana Farber Cancer Institute (DFCI). Recommended reads Here’s the new WaPo

blastema

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

2023 stem cell predictions grades reflect wild year for regenerative medicine

stem cell predictions

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

woolly dog

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’
