title: Dying alone: a tale of rho.
abstract: In this issue of Cell Stem Cell, Chen et al. (2010) and Ohgushi et al. (2010) report that Rho-mediated actomyosin contractility underlies the proclivity of human embryonic stem cells to undergo apoptosis upon dissociation or during low-density propagation, a property that challenges their in vitro isolation and manipulation.
