Figure 5.

A representation (not to scale) of the satellite cell, marked by Pax7, in its niche on the muscle fiber under the basal lamina in proximity to a blood vessel. Cell adhesion molecules, signals received from surrounding tissues, and molecules secreted by the satellite cell that regulate the niche and promote the quiescent state, discussed in the text, are illustrated. IGF, insulin-like growth factor; M CADH, M-cadherin.
