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 …

Big stem cell news: dynamic duo of all-chemical direct reprogramming reports

Neurons-created-from-ciNSC

There’s some big, positive news on the stem cell front today. 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 small molecules was able to turn them directly into …

Transdifferentiation makes a major advance: direct reprogramming of fibroblasts to oligodendrocyte progenitors

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 …

Defining epigenetic reprogramming, cellular reprogramming & rejuvenation

epigenetic reprogramming

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 …

Weekly reads: reprogramming hearing loss, heart disease, eye drops, sickle cell

Regener-Eyes, eye drops

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 …

Weekly reads: genome sequencing, chemical reprogramming 2.0

Human genome sequencing

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 …

Perspectives on David Sinclair anti-aging Cell pub & in vivo reprogramming

methuselah mouse, anti-aging

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 …

humans with tails

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 …

Sherley patent for reprogramming method like STAP cells

ASCTC

A new patent has been awarded to James Sherley for a very unusual method claimed for making induced pluripotent stem (iPS) cells. The patent, No. 8,759,098, claims that a single non-genetic chemical agent, xanthine, can by itself reprogram adult stem cells (ASC) into iPS cells (aka iPSCs; see image they released at left). Surprising patent, huh? Another …

Cool Cell Stem Cell Paper From Ishii Team on Histones & Reprogramming

Two of my favorite things are stem cells and histones. When they both come together in one paper and it’s in my favorite journal, Cell Stem Cell, you’ve got my full attention. My own lab is especially interested in the roles of histones and Myc in stem cells. So when I saw a paper a paper from …
