SP-litting the satellite niche to repopulate muscle.
Multiple myogenic populations have been highlighted in past publications. In this issue of Cell Stem Cell, Tanaka et al. (2009) advance our understanding of the cells that contribute to muscle regeneration by identifying an ABCG2-expressing population that exhibits excellent engraftment potential, particularly within the satellite cell niche.
