Abstract

Circumventing genomic modification in induced pluripotent stem cell (iPSC) derivation is a clear requirement to realize safe clinical applications. In this issue of Cell Stem Cell, Ichida et al., (2009) describe a small molecule capable of replacing Sox2, offering insight into the reprogramming process.
