How does one keep up with all the regenerative medicine and stem cell happenings? There is always something happening in the stem cell and regenerative medicine field ranging from science to policy matters. This post is an update on some recent stem cell happenings that I see as notable or interesting. New Pubs Direct reprogramming pub. One of the more interesting recent papers was from direct reprogramming guru Marius Wernig as his team came out with a new transdifferentiation paper that strikingly reports conversion …Read More

Today marks nearing the completion of a full circle for one of science’s biggest controversies: the STAP cell fiasco. Today STAP cells are completely refuted with the publication of two new papers in Nature and we know much more–with some notable gaps still–about what went wrong. In January of last year, an international team of collaborators from RIKEN in Japan and Harvard/Brigham & Women’s Hospital (including the lab of Charles Vacanti where the STAP idea reportedly originated) here in the US published two Nature …Read More

It seems like Fridays are always a good time for reflection. It’s not like the scientist’s week ends on Friday sad to say, but still at least we can pause momentarily TGIF style and reflect on the maelstrom that is our lives, while cracking open another diet Coke or pouring another cup of coffee. This week was a great one for getting into some intense discussions with other scientists both in person and electronically. CRISPR the talk of the biology town. Everyone is talking …Read More

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 a number of pathological conditions including Multiple Sclerosis (MS) and spinal cord injury (SCI). The two teams included one from Case Western Reserve University School of Medicine led by Paul …Read More
