Satellite cells are crucial for maintaining muscle homeostasis and for regeneration following injury. In this issue, Kuang et al. (2007) reveal that muscle satellite cells are a heterogeneous mixture of stem cells and committed myogenic progenitors. They show that asymmetric division of stem cells in the satellite cell niche is a mechanism for generating these two populations. © 2007 Elsevier Inc. All rights reserved.
