With controversy over her groundbreaking stem cell research refusing to die down, a Japanese scientist has agreed to retract one of her two papers on the study that was published in the journal Nature.
Haruko Obokata, 30, was feted after unveiling research that appeared to show a straightforward way to re-programme adult cells to become a kind of stem cell.
AdvertisementStem cells are precursors that are capable of developing into any other cell in the human body, and a readily manufacturable supply of them could one day help meet a need for transplant tissues, or even whole organs.
But within weeks of her paper on so-called Stimulus-Triggered Acquisition of Pluripotency (STAP) cells being published, questions began to emerge, with fellow scientists saying they could not replicate her results.
Riken, the respected research institute that sponsored the study, has urged her to withdraw her two papers, after concluding that she fabricated at least some of the data.
Obokata has agreed with her co-authors to a partial retraction, saying: "I don't oppose withdrawing one of the" papers, according to the Yomiuri Shimbun, Kyodo News and other media.
But her lawyer said that she won't withdraw the main paper, and insists she successfully created STAP cells on several occasions.
The paper to be withdrawn noted the versatility of the cells, while the other paper summed up the cells' characteristics and method of making them.
Immediate confirmation of the news reports were not available.
