Stem cell papers retracted
Researchers admit mistakes in work on easy method for making STAP cells
Researchers who claimed to have discovered STAP cells — stem cells made simply by stressing cells with a squeeze or with a brief plunge in acid — are pulling their papers from the journal Nature. The scientists say that mistakes in the work now make them doubt the existence of such cells.
“These multiple errors impair the credibility of the study as a whole and we are unable to say without doubt whether the [STAP cell] phenomenon is real,” the researchers write in the July 3 Nature.
