Riken Says Some Data Falsified in Stem-Cell Studies

Japan’s Riken research center said some data were falsified in a pair of studies that had outlined a simpler, quicker way of making stem cells.
Haruko Obokata, who had led the studies, was solely responsible for the misconduct, Riken’s investigation committee said in documents provided at a Tokyo briefing today. Co-authors Teruhiko Wakayama at University of Yamanashi and Yoshiki Sasai at Riken bear “heavy responsibility” for allowing the papers to be submitted to the journal Nature without verifying the accuracy of the data, the committee concluded.
