Asymmetric Distribution of Primary Cilia Allocates Satellite Cells for Self-Renewal
Regeneration of vertebrate skeletal muscles requires satellite cells, a population of stem cells that are quiescent in normal conditions and divide, differentiate, and self-renew upon activation triggered by exercise, injury, and degenerative diseases. Satellite cell self-renewal is essential for long-term tissue homeostasis, and previous work has identified a number of external cues that contr...
متن کاملAsymmetric Self-Renewal and Commitment of Satellite Stem Cells in Muscle
Satellite cells play a central role in mediating the growth and regeneration of skeletal muscle. However, whether satellite cells are stem cells, committed progenitors, or dedifferentiated myoblasts has remained unclear. Using Myf5-Cre and ROSA26-YFP Cre-reporter alleles, we observed that in vivo 10% of sublaminar Pax7-expressing satellite cells have never expressed Myf5. Moreover, we found tha...
متن کاملbeta-Catenin promotes self-renewal of skeletal-muscle satellite cells.
Satellite cells are the resident stem cells of adult skeletal muscle. As with all stem cells, how the choice between self-renewal or differentiation is controlled is central to understanding their function. Here, we have explored the role of beta-catenin in determining the fate of myogenic satellite cells. Satellite cells express beta-catenin, and expression is maintained as they activate and u...
متن کاملMuscle satellite cell heterogeneity and self-renewal
Adult skeletal muscle possesses extraordinary regeneration capacities. After muscle injury or exercise, large numbers of newly formed muscle fibers are generated within a week as a result of expansion and differentiation of a self-renewing pool of muscle stem cells termed muscle satellite cells. Normally, satellite cells are mitotically quiescent and reside beneath the basal lamina of muscle fi...
متن کاملSelf-Renewal of Stem Cells
Asymmetric division is one of the most fundamental characteristics of adult stem cells , which ensures one daughter cell maintains stem cell status and the other daughter cell becomes committed to differentiation. New data emerged recently that allow us to conclude that asymmetric division has another important aspect: it enables self-maintenance of stem cells.
