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 […]

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

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

When Jacob Hanna says “radically deterministic” cellular reprogramming, what does he mean? Jacob Hanna’s lab recently published a very high profile Nature paper on nearly 100% efficient iPS cell formation based on targeting a factor called Mbd3. This super efficiency is a major departure from past reported efficiencies. This morning here at the Till &

How important is the new development of all chemical reprogramming to make iPS cells? The group led by Hongkui Deng at Peking University in Beijing reported in Science that they used 7 chemicals to make what appear to be mouse iPS cells. I’m hearing a wide range of opinions directly from people in the know. What’s

It’s always fun to see startups with cool ideas in the regenerative medicine space and a new one called GC Therapeutics got some nice coverage this week. What do you think the name of this firm stands for? I have one main idea I mention below. Before we jump into it, I want to introduce
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

Induced pluripotent stem cells or iPS cells just might be the most exciting development in the stem cell field over the last 15 years. They have unique potential for clinical impact for regenerative medicine too. This may manifest both through their use to produce differentiated cellular therapies and indirectly via disease modeling as well as

In any given field of biomedical science like stem cell research and regenerative medicine, it’s very useful if you can accurately predict the future. It seems, though, that predictions are far more difficult within the more exciting and rapidly-changing fields. The field of stem cells and regenerative medicine fits that bill. Past stem cell research
