Japanese scientist withdraws 'groundbreaking' stem cell research
A Japanese scientist has asked for the findings of his groundbreaking study in stem cells to be withdrawn amid doubts over its quality.
According to Reuters news agency, Prof Teruhiko Wakayama of the University of Yamanashi told Japanese TV that when he was conducting the experiment, he believed that it was absolutely right, but many mistakes have emerged which has led him to withdraw the research paper, the BBC reported.
Several questions have been raised about the images used in the scientific report which claimed that dipping skin cells in acid could cheaply and quickly convert them into stem cells.
The original study, which was published in the journal Nature, had found that stem cells no longer needed to be taken from embryos or made by complicated and costly genetic tampering, and had been hailed as "remarkable" and as a "major scientific discovery".
