A reprogramming rush

摘要

In the most recent of his series of stunning articles on induced pluripotent stem (iPS) cells (T. Aoi et al. Science doi: 10.1126/sci-ence. 1154884; 2008), Shinya Yamanaka made a couple of small mistakes. Happily, he has since given plausible explanations for the mistakes, and has effectively argued that they do not affect the article's central conclusions - thus heading off worries (and one unsubstantiated accusation) that the errors signalled deeper problems with the article.
