Perspectives on final RIKEN report on STAP cell scandal & what comes next

STAP-cells-FIgure

The Japanese research institute RIKEN has come full circle in a way on the STAP cell scandal. Note that the STAP papers included not only authors from RIKEN, but also from Brigham and Women’s Hospital/Harvard Medical School. With its final report released today (also a powerpoint of images were released including the one showing a […]

Obokata Can’t Reproduce STAP Cells

Obokata-press-conference

Signaling a nightmare ending to what was originally a fairy tale scientific story, the Japanese press (e.g. here) are reporting that Haruko Obokata has herself been unable to make STAP cells again as part of a RIKEN team testing STAP under watchful supervision. In advance of a scheduled RIKEN press conference tomorrow, newspapers including Asahi Shimbun are

Harvard STAP cell authors release new protocol, affirm belief in phenomenon

STAP-stem-cells

Even as everyone was going through the Science and Nature reviews of the rejected STAP papers this week, something else on the STAP front that happened last week. What’s up? Well, the STAP Nature papers are retracted, RIKEN CDB is going to be reorganized, RIKEN CDB has tried at least 22 times to make STAP

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

GFP+-germ-cells

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

TJO

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

Wild History of VSELs Predicts Future of STAP Cells?

VSEL-cover-image

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 Report Is Virtual Acid Bath of Criticism for Obokata

si-Haruko

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
