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 […]
Can you learn important things about stem cells on Reddit? Yes, you can, but it’s a wild experience at times. Researchers may often think about stem cells through the lens of traditional routes of communication like academic journals, but laypeople turn elsewhere to learn about regenerative medicine. This includes digging into stem cells on Reddit.

What happens during brain aging and how can we tell if dementia is coming? Are there particular early hallmarks? There are an increasing number of medical tests for predicting or detecting dementia. Alzheimer’s disease can often be detected early. But what do patients or their doctors do with such information? Until recently there weren’t any

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

Readers of The Niche have asked me many questions about stem cells for autoimmune disease but the puzzle of why women get these conditions more often than men hasn’t come up before here. For instance, why is MS so much more common in women than men? It’s remained somewhat of a mystery over the years.
A reader of The Niche recently asked me, “What about stem cells for deafness?” It’s a great question and, as they pointed out, stem cells for vision loss gets much more attention. I’ve covered the translational progress of stem cells to treat many diseases but there has been less progress for deafness in the regenerative

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.
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
