Because Pax7 is a canonical marker for quiescent MuSC8, the greater frequency of Pax7+ cells implies that MuSCs have undergone adult myogenesis and asymmetric division to increase self-renewal of MuSCs following ischemia to replenish the pool of quiescent MuSCs to continue regenerating and for future rounds of regeneration. Here, PAX7 is linked to ischemia.
