A day after we published the cover letter and peer review reports about the STAP stem cell paper rejected by Science, Science‘s news section has published the same material for the version rejected by Nature.
From Science‘s news story about the document:
The Nature reviewers call the manuscripts and the results they describe “very interesting,” “potentially groundbreaking,” “highly provocative,” and “truly remarkable.” In the papers, Obokata, who works at the RIKEN Center for Developmental Biology (CDB) in Kobe, and her coauthors claimed that bathing blood cells from newborn mice in a mildly acidic solution could prompt them to become powerful stem cells. They dubbed the phenomenon “stimulus-triggered acquisition of pluripotency,” or STAP.
All three Nature reviewers concluded that the data presented in the submitted manuscripts were not enough to support such radical claims. “I would recommend the authors to be extremely cautious in their claims …. The authors should look into the actual effect that the treatment elicits in the genome and they should assess genomic instability,” one writes. “There are several issues that I consider should be clarified beyond doubt because of the potential revolutionary nature of the observations,” writes another.
