title: Self-renewal made simple.
abstract: Embryonic stem cells (ESCs) are prone to differentiation in culture, suggesting that maintenance of the pluripotent state must be actively induced. In a recent issue of Nature, Ying et al. (2008) use soluble small molecules to inhibit pro-differentiation signals and reveal ESC self-renewal as a default cell fate.
