stem cells differentiating into neurons and glia

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 …

How many stem cells do we have & can you run out?

gut stem cells

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 …

Answering reader questions: snorting stem cells, Regenexx, exosomes

Brain-PET-scan, stem cells

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 …

Legos for stem cells Fig 1b

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 …

Morinaga et al Nature 2021 Stem cells and hair loss

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 …

Prop 14 California: Big Expectations for CIRM 3.0

cirm prop 14 california millan allday knoepfler

Approval of Prop 14 California last month to renew CIRM was one of the biggest state election developments of 2020. Yet it didn’t get much news coverage somehow. The exception is David Jensen over at California Stem Cell Report, who has been a great source of information about the various news surrounding Prop 14 and …

hamazaki et al nature fig 2b induction of oocytes from es cells

What to read when there are almost an endless number of stem cell and regenerative medicine pubs? Here are some suggestions including what I would say is a very unusual Nature paper on making egg cells from stem cells. If this could be done safely with human cells all the way to functional eggs, would …
