STAP cell mixup. I don’t really hear from almost anyone who fully believes in the STAP cell thing anymore. The most common thing I do hear is from people assuming STAP is largely or entirely wrong and asking, “what really happened?” There’s still a chance that STAP is real, but if I were in Vegas or at the race track I’d put the odds in the single digits at this point. Betting on STAP to be entire

STAP spheres nice and green? Purported STAP stem cells. Dr. Ken Lee’s lab has done some very important validation attempts on STAP cells and has posted them on ResearchGate. To my knowledge, his lab’s STAP experiments are the ones in the public domain that most closely matched the methods of the Nature STAP papers. Dr. Lee submitted the work to Nature Brief Communications Arising on STAP cells, bu

STAP Cell Protocol Page from Charles Vacanti lab. The Vacanti Lab at Brigham and Women’s Hospital/Harvard Medical School has now posted online their own version of the STAP cell production protocol. The thing that first struck me most strongly about this published protocol is that it is not the same protocol reported in the Nature papers and it also is not the same as the recently posted RIKEN STA

I’m hearing from multiple sources that momentum is building in Japan and even inside RIKEN itself for retraction of the STAP cell papers. This whole situation is a tragedy on so many levels and has become a no-win situation, but is it so bad at this point that retraction could possibly be the least terrible of the entirely bad array of options? Why would some folks in Japan and even inside RIKEN t

Are the Nature STAP stem cell papers compromised? Could Nature‘s investigation conclude with something as serious as retraction or rather a mild slap on the wrist? Somewhere in between? (note you may find this update post from 2020 to be of interest: Whatever happened to the STAP cell scientists including Haruko Obokata?) Why is this question even being raised? A large number of potentially seriou

Supposed STAP stem cells. We know quite a bit more about the Nature papers on stress-induced STAP stem cells than we did just a couple weeks ago when they were published, but there are many crucial outstanding questions too and odd things that remain unresolved. Below are my top STAP stem cell oddities. 10. Dr. Vacanti says that STAP stem cells are probably the same as “spore stem cells”, a contro

This is a crowdsource page for people who want to post their findings on their attempts to validate the STAP stem cell ( ＳＴＡＰ細胞) method.  I’m going to color successful or even moderately encouraging reports green and failures/discouraging results in red. *For those with longer attention spans, see some additional important considerations for this crowdsourcing effort at the bottom of this page.

The only designation of Mr. Moriuchi’s educational background that I found was in a letter to the editor where he lists himself as M.P.H. Unless he has finished a medical degree or Ph.D. since 2004 (which is quite possible), he should be addressed as Mr. Moriuchi and not Dr. Moriuchi as the Harvard spokesperson addressed him. N Engl J Med 2004; 351:831-832August 19, 2004 To the Editor: A recent me

Back in late August, Liveyon leader John Kosolcharoen pleaded to federal charges on stem cells. What was Liveyon? Liveyon was a splashy umbilical cord stem cell supplier company. I don’t know if the company is still active now. One of its core products ended up sending dozens of people to…
