title: Nanog: a new recruit to the embryonic stem cell orchestra.
abstract: In this issue of Cell, and add a new transcriptional operating system to the known Oct4 and Stat3 systems required for early embryonal stem cell potency and self-renewal. Nanog, a homeobox transcription factor, plays a crucial role in the second embryonic cell fate specification following formation of the blastocyst.
