Won’t You Be My Neighbor? Muscle Stem Cells Recruit Endothelial Cells to Their Niche

The maintenance of a pool of quiescent satellite cells (muscle stem cells) is necessary for long-term muscle health. In this issue of Cell Stem Cell, Verma et al. (2018) show that satellite cells recruit endothelial cells to create a vascular niche and that cross-talk between endothelial and satellite cells is vital for replenishment and maintenance of quiescent satellite cells.
