The ultimate fate of the two Nature STAP cell papers remains in troubled limbo. One of the senior STAP cell authors, Dr. Sasai, held a news conference yesterday in Japan that included a call for the papers to be retracted. He was variously quoted as believing in STAP cells or alternatively as just thinking it […]

Very small embryonic-like stem cells aka VSELs are reported to be tiny adult stem cells that are pluripotent or non-existent depending on whom you talk to most recently or which paper you just read. These very controversial cells (which I once compared to the Sasquatch) have a wildly fluctuating history with their existence on multiple occasions

What is Harvard’s role in the STAP cell mess? If you have been living in a cave somewhere for the last 6 weeks, to catch you up to speed, an international collaborative team published two papers in Nature reporting the creation of powerful stem cells–so-called STAP stem cells–via a simple method of stressing ordinary differentiated

Update: A commenter said they’d prefer a different format to the graphing of these STAP cell poll results. Even though they weren’t exactly nice about it to put it mildly, I thought they had a good point so a hat tip to them and below is an attempt at a new graph style that makes

The controversial STAP stem cell papers published in Nature had authors both from RIKEN in Japan and Brigham and Women’s Hospital/Harvard. What is the RIKEN interim take on the STAP cell situation? We’ve had pretty much silence from Harvard itself on this matter publicly. Dr. Charles Vacanti, senior author on one of the STAP papers,
