Are there endogenous adult heart stem cells that are useful in cardiac disease or can stem cell infusions help ailing hearts? As to the first question, the adult heart does not appear to have meaningful numbers of true stem cells. Further, testing the idea of infusions of stem cells for heart disease has so far been giving …

We’ll start with a story related to possible research misconduct, Stanford’s President Marc Tessier-Lavigne, and Science Magazine. In some ways the news on Science itself could be the bigger long-term story. Marc Tessier-Lavigne pub investigation, Science oops moment Here’s some of the coverage: Stanford investigates potential misconduct in president’s research, Science. Multiple publications of Marc Tessier-Lavigne …

Earlier this year Chinese researcher He Jiankui finished his prison sentence. When I saw that news I wondered about the next chapter for him. It seems he’s already back in the lab doing genetics research. At least that’s according to a blog by He Jiankui himself. Can we trust that what he has written on his website is …

The National Academy of Medicine elected a cohort of new members including three stem cell researchers. It’s great to see our field and these great scientists get recognition. The new NAM stem cell researchers include Sally Temple, Connie Eaves, and Tippie MacKenzie. Here’s a little bit about each of them. Dr. Temple is a stem cell biologist …

I took a cross-country road trip earlier this month that was pretty amazing and barely thought about stem cell research for the first time in years. We did run across one stem cell clinic in Florida by accident. I’ll write about that trip soon, but first we have our weekly reads including some very cool …

The recent news of Vertex Pharma buying small stem cell biotech ViaCyte and Doug Melton moving to Vertex brought to mind an old stem cell biotech called Advanced Cell Technology (ACT) and its leader, stem cell biologist Dr. Robert Lanza. Years ago, big pharma firm Astellas bought ACT and Lanza moved to be a leader of regenerative …
Sometimes it’s useful to ask questions like, “How many stem cells are in the human body?” As we try to answer them we end up going through key aspects of cell biology and stem cell identity more generally. How many stem cells in the human body? It might seem like possibly an easy question at …
