Effects of skeletal muscle satellite cells on muscle fiber lesions / 中国组织工程研究

ABSTRACT

BACKGROUND: Skeletal muscle satellite cells have been found to possess the potential of stem cells that have the ability to self-renew with the roles of repair and regeneration. Therefore, it can be used to treat myofibrosis. OBJECTIVE: To explore the function, molecular regulation and related mechanisms of skeletal muscle satellite cells, and to promote the repair and regeneration of skeletal muscle fibers, thereby providing new ideas and intervention strategies for the rehabilitation and treatment of skeletal muscle injury. METHODS: A computer-based online search was conducted in PubMed, Mendeley, Google Scholar, and CNKI databases from 1995 to November 2016 for the relevant literature using the keywords of "skeletal muscle,satellite cells, stem cell, muscle repair". Data screening, processing, and summarization were performed. RESULTS AND CONCLUSION: According to the inclusion criteria, 51 eligible articles were enrolled. Analysis results show that skeletal muscle satellite cells are closely related to muscle fiber lesions. Based on the mechanism of skeletal muscle lesions, the regeneration and repair mechanisms of skeletal muscle satellite cells are explored. Skeletal muscle tissue is a functional and sound system that can regenerate and repair through skeletal muscle satellite cells. The function of skeletal muscle satellite cells is controlled by intracellular and extracellular information networks, which can enhance endogenous satellite cell viability. When the skeletal muscle is injured or malnourished, the viability of skeletal muscle satellite cells is inhibited, further inducing skeletal muscle fiber degeneration. Therefore, skeletal muscle fiber lesions can be treated through skeletal muscle satellite cell transplantation and stimulating the viability of endogenous skeletal muscle satellite cells, which provides intervention strategies for skeletal muscle repair and regeneration.
