STAP cells succumb to pressure4 @+ d/ I# m# @# ?+ r, c
# G% m6 Q" K- L$ k" c* c, _5 W2 A# ?Two papers that electrified—and confused—the stem cell field just 6 months ago appear to have lost their last defenders. Last week, lead author Haruko Obokata of the RIKEN Center for Developmental Biology (CDB) in Kobe, Japan, agreed to retract a Nature paper that described a startlingly easy way to produce stem cells; she had agreed to the retraction of a related paper a week earlier. Obokata's Japanese co-authors had previously called for the moves, and it has been widely reported that another key author, Charles Vacanti, a tissue engineering specialist at Brigham and Women's Hospital in Boston, has agreed to the retractions as well. (He declined to speak with Science.) |
