Summary
A Japanese investigating committee concluded that image manipulation and the use of pictures from an old experiment constitute research misconduct in one of two papers reporting a new method of deriving stem cells. The head of RIKEN says he will call for the retraction of the paper if the committee's findings are confirmed on appeal. The lead author rejects the misconduct charges, maintains the problems resulted from simple mistakes, and contends the new cells really exist.
