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 […]

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

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

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

I’ve been teaching Histology here at UC Davis School of Medicine for more than 12 years and I lecture on skin among other topics so I’ve made more than one labeled diagram of the skin over the years. I’ve included some in this post. First, below you can see a zoomed0out view of fingertip with

When people find out that I’m a stem cell researcher, a common question is whether there’s something they can take that is a stem cell activator. I’ve written before about whether there are stem cell boosts that one can do to try to be healthier. Sleep, stem cell activator and clonality Mostly when I bring

A new stem cells for ALS treatment trial represents a big step forward. It’s early days still but this trial shows feasibility and provides a helpful foundation for moving forward. It also highlights challenges. The work is from a team led by Clive Svendsen. Stem cells for ALS treatment trial Here’s the study. Transplantation of
When I’m asked about the most promising areas of stem cell clinical research, cell therapy for type I diabetes is near the top including work by a biotech called ViaCyte. Other firms are in the mix too, boosting the overall odds of success in the coming decade. It’s really that promising even though there are

The first time I heard CAR-T cells referred to as a regenerative medicine it made me stop and think. Are CAR-T therapies really a type of regenerative medicine? Generally, CAR-T cells are a designer immune cell therapy. They work by killing cancer cells and that’s what came to mind to me. I don’t tend to
