I hadn’t remembered the history of the philosopher’s stone until reading a new review article about stem cells and aging. Here’s the article. Is the philosopher’s stone to rejuvenate blood stem cells an epigenetic regulator? Nature Aging. This preview kind of piece discusses how inhibiting a specific factor called PHF6 can “rejuvenate” HSCs in mice. […]

What are examples of unipotent and multipotent stem cells? More broadly, stem cells have the ability to do two key things. They can make more of themselves through a process called self-renewal. Also, they have the ability to differentiate into other cell types. This latter property is called potency. Taken together this means by definition

As both a scientist who works on stem cells, cancer, and CRISPR, and a research advocate I’ve been fortunate to meet many patient advocates over the years. Some have been participants in clinical trials themselves. Benefits & risks of clinical trial participation It is very sobering to find out that a clinical trial participant has

I wrote recently about how political pressure on FDA Commissioner Stephen Hahn in 2020 may have helped the Texas firm Direct Biologics move their product ExoFlo forward inside the agency. Today I analyze the ExoFlo Phase I clinical trial paper used in that push on Hahn to get the firm the IND for a Phase II

The FDA has finally filed an appeal of the Cell Surgical Network lawsuit verdict. It took them a very long time for some reason. The stem cell clinic chain Cell Surgical Network and other defendants had prevailed in a federal district court here in California in front of Judge Jesus Bernal. Their adipose cell product, stromal

Today’s post is on the lighter side with some humor on funny autocorrect fails related to science. It’s surprising sometimes how far certain tools can lag behind cutting-edge science. Spellcheck tools are useful, of course, but they don’t always know what to do with STEM words. The same is true of tools like Grammarly, although it

The National Academy of Medicine elected a cohort of new members including three stem cell researchers. It’s great to see our field and these great scientists get recognition. The new NAM stem cell researchers include Sally Temple, Connie Eaves, and Tippie MacKenzie. Here’s a little bit about each of them. Dr. Temple is a stem cell biologist

Germ or sex cells have many important implications for health and research. In today’s post the goal is to provide a helpful, comprehensive overview of these remarkable cells. Where does research on these cells stand today? It’s an exciting time. What are sex cells? | Are sex cells haploid or diploid? | Why are germ cells

I get great questions from readers of The Niche including, “Are there multiple ways to get stem cells?” The answer is “yes.” Why is this important? The different sources of stem cells can impact both their use in basic research and their potential clinically. My goal in today’s post is to give an overview of

When I first started The Niche more than a dozen years ago, I hoped we’d see a Parkinson’s disease stem cell therapy by now. A proven one. I was a little too optimistic back then. Now in 2022, I know much better how hard translation to the bedside can be in general. Still, I’m hopeful.
