Sally Temple on adult RPEs for vision impairment, IND, & more

Sally-Temple-cells

At the recent RPI stem cell and bioengineering meeting, the Neural Stem Cell Institute’s Sally Temple talked about her group’s intriguing retinal pigmented epithelial cell (RPE) research. With the broad focus of attention in the world of RPEs mostly on those derived from either human ESC or IPSC, it was exciting to here about the […]

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

Shocker: FDA views treatment with ethylene oxide, a highly toxic carcinogen, & irradiation as minimal manipulation

What does the FDA define as “minimally manipulated” when it comes to biologics such as stem cells? You will be shocked to find out, but they include irradiation and treatment with the super toxin/carcinogen, ethylene oxide. In a recent post I discussed the issue of an apparent “minimal manipulation” exception (some might even call it a

Irv Weissman’s early career and the mentors that made the difference for him in his own words

It has been a week to think about mentors and I posted somewhat autobiographically on how to find and be a good mentor a few days ago. Also along these lines, I asked one of the great mentors of all time, Irv Weissman, about his early career and who were the mentors that made the
