Abstract

Tumor necrosis factor-α (TNF-α) has complex effects on muscle regeneration. In this issue of Cell Stem Cell, Palacios et al. (2010) report that TNF-α-activated p38α kinase controls differentiation of muscle stem cells by promoting polycomb repressive complex 2 (PRC2) silencing of the Pax7 promoter.
