STAP cell research paper questioned

TOKYO, Japan - File photo taken in January 2014 in Kobe, Hyogo Prefecture, shows Haruko Obokata (L), a scientist at the Riken Center for Developmental Biology, and University of Yamanashi professor Teruhiko Wakayama, at a press conference on "stimulus-triggered acquisition of pluripotency," or STAP, a method of generating pluripotent cells. Wakayama said March 10, 2014, he has told his co-authors including Obokata that their research paper on STAP cells should be retracted, citing the lack of credibility of some data used in the research.
