Professor Teruhiko Wakayama, the scientist behind the recent apparent discovery of a novel way to induce pluripotent stem cells ((iPSCs)), now says the published study should be withdrawn and reanalyzed due to the emergence of mistakes.
The study was first reported on January 28 and created a global sensation because it showed that normal cells could be transformed into stem cells by dipping them in acid. Questions soon arose about certain images Prof. Wakayama used in the paper. Other research groups have been unable to reproduce her findings thereby adding to the controversy.
The situation is attracting intense media scrutiny because of another scandal that happened several years ago when a self-taught scientist with a degree in nursing treated a heart disease patient with cardiac cells derived from the patient's own iPCSs. He was eventually dismissed from his position at the University of Tokyo.
