Obokata OKs Retraction of Nature STAP Cell Letter, Not Article

Obokata-press-conference

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 …

Perspectives on Lee Lab F1000 Paper that STAP Cell Method Does Not Work

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 …

Did Obokata get a fair shake on STAP cell mess?

Poll #7 on STAP cells shows little change with few believers in Japan

STAP-poll-7

Since the STAP Nature papers were published, I’ve been doing a non-scientific Internet poll on the general level of “belief” in STAP. Poll #7 has now closed with 930 votes and a fairly steady level of skepticism for the last month or so. Poll#7 results from amongst Japanese respondents (7J) shows almost nobody in Japan …

Obokata STAP news conference: thoughts, questions & open discussion

Obokata-press-conference

Dr. Haruko Obokata held a news conference today in Japan about the STAP cell controversy. It was very painful to watch. I’m a softy so at moments I felt somewhat sad for her as I watched, but as a scientist I have to say the STAP situation has been very bad for the stem cell …
