Controversial Stem Cell Studies Retracted

From the WebMD Archives

July 3, 2014 -- Fraud allegations and waves of criticism from experts have led the journal Nature to withdraw two papers that claimed to describe a breakthrough in stem cell creation.

American and Japanese researchers said they had created stem cells capable of becoming any organ or tissue in the body simply by dipping white blood cells from young mice in an acid bath, the Boston Globe reported.

However, an investigation discovered errors and evidence of scientific misconduct in the papers describing the creation of what the researchers called STAP stem cells.

"Ongoing studies are investigating this phenomenon afresh, but given the extensive nature of the errors currently found, we consider it appropriate to retract both papers," Nature said in a retraction notice published Wednesday, the Globe reported.
