Japanese news media are reporting that Haruko Obokata and other key authors have agreed to retract the Nature STAP cell letter, but not the Nature article. This is a major development and a peculiar one because to many in the field it is the Nature STAP cell article that is the more flawed of the two Nature papers on STAP. Why would […]

A paper has been published reporting that repeated attempts to make so-called “acid bath stem cells” have failed. At the end of January it was claimed in two Nature papers that a mild acid treatment created pluripotent or even totipotent stem cells that that the authors termed “STAP cells” or “STAP stem cells” (collectively referred

What’s going on with the STAP cell situation now that it is into its third month? It’s getting worse instead of better or clearer, at least in part due to RIKEN’s incomplete investigation. What’s going on with STAP? New RIKEN Press Conference RIKEN reportedly held an odd sort of limited press conference today that TJO

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

RIKEN Institute in Japan has formally announced the complete findings of its investigation into the STAP cell research, Haruko Obokata, and Nature papers. RIKEN almost entirely blamed Obokata for the STAP mess in this report and they didn’t mince words. The RIKEN report alleged that Obokata had engaged in two instances of “research misconduct” as

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

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,

A small group of the STAP authors via RIKEN have now released a detailed protocol also available at Nature Protocol Exchange for making STAP stem cells entitled “Essential technical tips for STAP cell conversion culture from somatic cells”. This comes about 5 weeks after publication of their Nature STAP stem cell papers. 2020 update: With the 4th and

People have been taking a long look over the last 24 hours or so at the STAP stem cell patent application filed by Charles Vacanti, his brother, Obokata, and others. Any reactions? I don’t know much about patents so I’d be curious of your impressions. New STAP paper troubles? I’m hearing through the stem grapevine

What’s the latest on the now two-week-old STAP stem cell saga? More preliminary data from around the world. People continue to deposit their data into our crowdsourcing page with 8 reports so far and I know some of them are from top-notch labs. Only one of them is even slightly encouraging with a report of
