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

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

If you’ve never heard of the KRAS G12C mutation, it’s a particularly frightening mutation present in numerous cancers. Like the MYC oncogene, many people view mutations in RAS as undruggable, but new efforts show some glimmers of hope. The drug Sotorasib has been approved by the FDA to target the KRAS G12C mutation. Here’s a

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.

It’s always great to read about stem cell clinical trials that are looking encouraging. Stem cell clinical trials Proving a new therapy is safe and effective is so challenging. Remarkably, there are more than 9,300 stem cell clinical trials listed for a “stem cell” search on Clinicaltrials.gov. Of course, not all of these are actual
I’m working to send out a big grant on Tuesday so I’m busier than ever but a few stem cell and regenerative medicine stories caught my eye. I can’t write grants 24/7 without a few breaks although sometimes it feels like that’s what I’m doing. Bat stem cell derivation Pluripotent bat stem cells as a
