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 […]
Does time seem somewhat warped to anyone else in 2020 even without having had COVID, which could alter brain function? It just seems like with everything going on that time simultaneously both drags and zooms by this year. One sort of reassuring element is that papers keep on being published so we can enjoy cool

What is direct reprogramming ? There’s some big, positive news on this stem cell front today. All chemical direct reprogramming Two new innovative papers both by teams led by Sheng Ding of Gladstone Institutes with UCSF report all-chemical direct reprogramming of human somatic cells. Ding’s team took skin cells and by exposing them to cocktails of

Back-to-back papers (here and here) in Nature Biotechnology report the transdifferentiation (now often simply referred to as “direct reprogramming”) of plain old fibroblasts into brain cells called oligodendrocyte progenitor cells (OPCs). OPCs are a remarkably useful kind of brain cell that generates myelin, which insulates nerves. OPCs are thought to have great therapeutic potential for
If you remember Monty Python, then you probably recall John Cleese. We’ll start with Cleese’s stem cell baloney. Not spam. Secret to eternal youth? John Cleese extols virtues of stem cell treatment, The Guardian. I’ve written before about John Cleese’s stem cell anti-aging efforts. As I told the author of The Guardian piece, I love
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.
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 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 warnings (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
