Web2.3 Self-Renewal of Muscle Progenitor Cell Reserves. Once resident satellite cells become cognizant of tissue damage, they rapidly transition into a proliferative state, … WebThe fact that certain mutations can enable normal progenitor cells to self-renew (Akala et al., 2008) suggests that mutations could reactivate self-renewal programs in residual non-tumorigenic cancer cells in some patients. Nonetheless, elimination of the cancer stem cell population in a tumor could lead to dramatically better clinical outcomes.
