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 […]

When you are a stem cell biologist and especially if you do a blog, you sometimes run across very strange things like a chimera cat. In this case, I stumbled on the whole topic of chimeric cats because I was searching for info on chimeric rats on Google. Of course, I was. It’s kind 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
Patients regularly reach out and ask me about something called HSCT. “What is HSCT?” and is it proven as a therapy? Often the patients asking about this have multiple sclerosis (MS) or some other autoimmune disease. I’m not a physician so I can’t give medical advice, but as a stem cell biologist here at UC

There was a time when I thought transdifferentiation based approaches might quickly move into clinical trials. Then things kind of cooled off. We didn’t see many papers reporting methods to transdifferentiate cells. I still think that this technology, sometimes called direct reprogramming, has major potential. A new paper on making human brain cells this way got

Exosome therapy is a still-experimental cell therapy approach aimed at treating specific diseases using secretions from cells. It’s novel since most attention on cell therapies has been given to using the actual cells themselves. In addition, this approach is a newer idea than using cells as the drug to treat diseases. Interestingly, the term “cell

A common question I hear from readers of The Niche is some version of, “Is stem cell therapy covered by insurance?” Sometimes they also ask about Medicare coverage. To be clear, I’m talking about unproven stem cell “therapies” here. The type clinics sell. It’s not FDA approved so generally insurance companies and Medicare will not

Histone proteins such as histone H3 are often popping up in science writing and news sometimes includes specific modified forms of H3 including one that we scientists call H3K27me3. What is in this article What is H3K27me3? | The histone code | H3K27ac and H3K27me3 function | H3K27 and human disease | References The goal of today’s post

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
