People often ask me about stem cells for autism or even their hope of an autism cure. I’ve explained that there is no new treatment for autism based on stem cells. There aren’t even mildly encouraging data. Note that it can be hurtful to the community to talk about an autism cure and disregarding neurodiversity. …
What is immune rejuvenation? How would that work and what would be the benefits? As we age, our immune systems can change in unhelpful and unhealthy ways. One such change is a drift in the balance of production of different kinds of immune cells. Such a shift can lead to too many of some immune …
Epigenetic reprogramming is a term used in cell biology that is increasingly ending up in news stories too. Unfortunately, some folks, especially in the cellular rejuvenation and anti-aging space, are getting this term and other things confused. Just to start off, epigenetic reprogramming does not specifically mean cellular rejuvenation. The goal of today’s post is …

It’s great finding stem cell videos on YouTube that are either excellent research talks or provide important information. I recently found one such video by Shiri Gur-Cohen, which I included below. Interesting data there and Shiri is such a compelling speaker. She also won The Niche image contest one year with a cool microscopy pic …

It’s mostly been a week of good and encouraging news in the regenerative medicine space including with gene therapies maybe with the exception of some eye drops warning (more below). There’s realistic hope for an approved sickle cell disease soon. I also see some long-term positive news on hearing loss research. Hematopoietic stem cell transplant …

I wrote earlier this week about genome sequencing of famous dead celebrities, pointing out that the trend seems full of ethical complexities. Genome news More broadly, sequencing the genomes of non-celebrities from hundreds or thousands of years ago can be important research. A new NYT piece covers such work on the Swahili people. Such research …

About twenty years ago a science story made big news of a so-called anti-aging Methuselah gene. Methuselah gene and anti-aging The claim was that this DNA conferred long life on people. Hence the name Methuselah, which refers to a man from the Bible who reportedly lived 969 years. The so-called Methuselah gene was at first not a …

Let’s start with a couple of new pieces on in vivo reprogramming. The idea here is to do something like making iPS cells but doing it inside organisms and not quite pushing cells all the way back to pluripotency. Just younger, healthier cells. Why do that? The goal is to achieve a kind of anti-aging …

We often don’t think of them that way but reproductive cells like sperm and egg are also relatives of stem cells, and it turns out that there are stem cells that make the reproductive cells too like sperm stem cells. Sperm and germ cell stem cells DNMT3A-dependent DNA methylation is required for spermatogonial stem cells …

A piece on human tails and how we lost them caught my eye so I’ll start my weekly reads with that. This week I had the fewest Zoom meetings in ages, which allowed me to get more work done in my own lab and more reading. How about that? I even had some in-person meetings …
