It’s been quite a ride doing this blog on stem cells and other technologies for more than a dozen years. So far it seems like I’ll keep it going. A large part of the reason is because of people needing good information about our field. Those people include scientists and physicians but also many in […]

Sometimes it’s useful to ask questions like, “How many stem cells are in the human body?” As we try to answer them we end up going through key aspects of cell biology and stem cell identity more generally. How many stem cells in the human body? It might seem like possibly an easy question at

One of the most interesting parts of running The Niche is that I get all these questions about stem cells and related matters from readers. I try to answer questions regularly by email, but sometimes the volume catches up with me. For that reason I periodically try to do posts answering such questions, which has

The other day I was talking with some folks about stem cell policy on Zoom, which was great, but one phrase from them jumped out at me and gave me a laugh. “Joe Rogan is the Gwyneth Paltrow for bros.” It also just rings true to me. Some readers of The Niche may remember that

I’ve been busy recently focusing more on grant and paper writing than reading papers on stem cells, but my piece on trying to de-extinct mammoths via cloning-like methods drew strong opinions on both sides. Recent news and resources on stem cells We’re still awaiting a verdict in the big California federal court case where the FDA is

The paper of the week is from Science on making ovarian follicles and actual eggs from stem cells. It’s just in mice, but this line of work tends to stir people up. We’ll dive into that in a moment. But first some good news. We’re up to 146 subscribers on our stem cell YouTube channel

The paper of the week is An isoform of Dicer protects mammalian stem cells against multiple RNA viruses published in Science. The take-home from the abstract is that the data, “demonstrate that mammalian stem cells can protect themselves from some RNA viruses by expressing an alternatively spliced isoform of the enzyme Dicer called aviD, which potentiates
The first of the month often brings loads of new papers as new issues of journals come out so we have a wave of new stem cell papers. By the way, be sure to enter our stem cell picture contest to try to win $100 or a bundle of stem cell swag. There’s less than

What’s the difference between multipotent stem cells, totipotent stem cells, and pluripotent stem cells? The goal of today’s post is to help you learn and be clear on the differences. What’s in this article Definition of stem cells |Totipotent vs pluripotent stem cells | Pluripotent stem cells | Multipotent stem cells | The best kind of stem

Sometimes patients or my students ask me, “What are the best stem cells?” what information are they looking for? I think they often are looking for the most powerful stem cells so perhaps they should be asking, “What are totipotent stem cells?” Other times it seems what patients specifically want to know is what might
