According to the report:
Embattled Japanese scientist Haruko Obokata has agreed to retract one of two STAP cell research papers from the journal Nature, while maintaining she will not retract the other major paper, her lawyer said Wednesday.
It is the first time that the 30-year-old researcher from the state-backed Riken institute has agreed to have a paper retracted in connection with the high-profile study that quickly drew questions and allegations of misconduct.
Along with Obokata, who led the study into the stimulus-triggered acquisition of pluripotency cells, two other main co-authors have given their consent to retract it, sources close to the matter said.
One of the co-authors of the articles, which came out in January, already has requested that both papers be retracted.
The Japan Times has a few more details, which suggest “Bidirectional developmental potential in reprogrammed cells with acquired pluripotency” is the paper to be pulled:
Of the three researchers, her lawyer said University of Yamanashi professor Teruhiko Wakayama is responsible for the paper Obokata has agreed to retract. He was engaged in all experiments, and Obokata wrote the paper under his guidance, lawyer Hideo Miki said.
She e-mailed the other main co-author, Yoshiki Sasai, deputy director of the Riken Center for Developmental Biology in Kobe, that she would have no problem if Wakayama wants to retract it, Miki said.
