If you take an ordinary cucumber and soak it in a mild acid solution of vinegar for a few weeks you get a pickle, which is where we find STAP stem cells. Recently, some scientists reported in Nature that if you take ordinary cells and soak them in a mild acid solution for 30 minutes, […]

A new article in the major Japanese newspaper, Asahi Shimbun, just came out suggest major intellectual property (IP) and patent issues related to stem cells including the new stress induced STAP stem cells. The piece is entitled provocatively enough “Global patent war looms with epoch-making discovery of STAP cells“. That’s strong language. The article begins

The STAP papers on making iPS like cells using acid treatment of differentiated cells really has people talking. See embryo at right made from GFP reporter STAP cells that glow green. As I said in my review of the papers yesterday, there are still some critical things we do not know about STAP cells and I

When a vendor of important reagents like antibody supplier Abcam charges big money, those high Abcam prices could negatively impact research in the long run. Some of the prices are so high that buying just a few antibodies could take up a small but meaningful slice of an entire R01 grant. Sky-high Abcam prices I’ve

Paolo Macchiarini is one of a small group of people in the stem cell universe whose misconduct has blown up in the press. Piero Anversa, Haruko Obokata, Hwang Woo-Suk, and some operators in the unproven stem cell clinic sphere come to mind. Macchiarini published quite a few seriously problematic papers, some of which just hung

Retraction Watch has been a great resource for those of us who have been following research misconduct. They widely cover and conduct research on retractions, corrections, and other developments in this space. Unfortunately, there’s been plenty to write about even just within the stem cell and cell therapy arena, which is my primary interest. Think
There seems to be a never-ending supply of stem cell for hair loss research but a new article invokes a novel mechanism. Stem cell for hair loss research and cell mechanics Here’s a recent news item about a PNAS paper: Coaxing hair growth in aging hair follicle stem cells, NW Now. A common theme is things

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

Dr. Paolo Macchiarini exemplifies how things can change quickly in the stem cell world and go from sky highs to deep lows. Stem cell rollercoasters Over the years, a few academic stem cell researchers as well as some operators in the unproven clinic sphere have had dizzying ups and downs. There’s John Kosolcharoen. His company
