摘要:

文题释义:
干细胞自我更新:干细胞特征之一,是细胞通过对称或不对称分裂,产生完全复制自身的子细胞的过程。
信号通路:是指当细胞里要发生某种反应时,信号从细胞外到细胞内传递信息后,细胞要根据这种信息来做出反应的现象。

背景:肌卫星细胞自我更新是肌纤维受损后,肌卫星细胞被激活参与骨骼肌纤维修复从而影响骨骼肌再生修复的重要环节。
目的:将肌卫星细胞自我更新及其相关信号调节研究进展进行综述。
方法:在PubMed、web of science数据库中进行相关文献检索,以“skeletal muscle, satellite cells,stem cell,muscle repair”及“signal pathway,self-renewal”为关键词进行检索,通过阅读文题和摘要进行初步筛选,排除与文章主题不相关的文献,最终纳入60篇文献进行结果分析。
结果与结论:①近年来,肌卫星细胞参与骨骼肌适应性改变过程越来越受到重视,其广泛且快速地被激活增殖产生肌肉细胞作用于骨骼肌损伤;②肌卫星细胞的自我更新机制的多样性和繁复性可通过调节肌卫星细胞的分化从而影节骨响骨骼肌的修复、再生等方面;③现阶段肌卫星细胞自我更新的相关研究大量与衰老相关,提搞肌卫星细胞激活程度、增加个体数量等研究,探索其参与组织再生与修复中的过程,具有较好的应用前景,但若要阐明其具体机制,还需更多深入研究和探索。

Abstract: BACKGROUND: The self-renewal of muscle satellite cells is an important part of the regeneration and repair of the skeletal muscle after muscle fiber damage. 
OBJECTIVE: To review the research progress of self-renewal and related signal regulation of myosatellite cells. 
METHODS: The relevant literatures were searched in PubMed and Web of Science database, using the keywords of “skeletal muscle, satellite cells, stem cell, muscle repair” and “signal pathway, self-renewal.” After reading titles and abstracts, the literatures that were not related to the theme of the article were excluded and finally, 60 literatures were included for result analysis. 
RESULTS AND CONCLUSION: In recent years, increasing attention has been paid to the involvement of muscle satellite cells in the adaptive process of skeletal muscle, which are widely and rapidly activated to generate muscle cells to act on skeletal muscle injury. The diversity and complexity of the self-renewal mechanism of muscle satellite cells can affect the repair and regeneration of skeletal muscle by regulating the differentiation of muscle satellite cells. At present, a large number of research on the self-renewal of muscle satellite cells are related to aging. A good application prospect is displayed by improving the activation degree of muscle satellite cells, increasing the number of individuals involved, and exploring their participation in  tissue regeneration and repair, but more in-depth research and exploration are needed to clarify the specific mechanism.

Key words: muscle, muscle satellite cell, skeletal muscle, skeletal muscle regeneration, signal pathway, RNA, protein, review
