Abstract:

Skeletal muscle satellite cells are considered to be the only stem cell source of adult skeletal muscle cells differentiation. It is generally in resting state. After stimulated, skeletal muscle satellite cells can be activated, proliferation and differentiation into muscle cells through the key signaling pathway, then participate in the formation of skeletal muscle and injury repair. Signaling pathways commonly involve in the process of proliferation and differentiation of skeletal muscle satellite cells.Such as Wnt and mTOR signaling pathways regulate satellite cell activity through cascade amplification, Notch and P38 MAPK signaling pathways are thought to be closely related to the resting state of satellite cells, JAK/STAT signaling pathway can cause different specific responses of satellite cells at different stages. These signaling pathways are linked to each other, and thus affect the growth and repair capacity of skeletal muscle satellite cells. In this paper, we reviewed the study progress of the effects of Wnt, Notch, P38 MAPK, mTOR, JAK/STAT signaling pathways on the proliferation and differentiation of skeletal muscle satellite cells, and laid a foundation for further study on the molecular mechanism of skeletal muscle formation and muscular development.
