摘要: 动物出生后骨骼肌在生长发育和再生过程中,卫星细胞发挥着十分重要的作用,其分化及形成肌纤维的类型与肉品质密切相关,wnt/β-连环蛋白(β-catenin)信号通路是调节此过程的重要信号通路。近几年,wnt/β-catenin信号通路在骨骼肌生长和再生过程中的作用及机制研究受到人们的重视,已积累了一些相关研究成果。本综述系统阐述了wnt/β-catenin信号通路在卫星细胞自我更新、分化以及肌纤维类型形成中的作用。

Abstract: Satellite cells are established as the major stem cells contributing to gowth and development as well as regeneration of skeletal muscle. Differentiation of satellite cell and muscle fiber type formation are closely related to meat quality. wnt/β-catenin is an important pathway regulating these events. Recently, more and more research focused on skeletal muscle growth and regeneration regulated by wnt/β-catenin. And many interesting results are published. The role of wnt/β-catenin in the differentiation of satellite cells into different type of muscle fiber and turn-over was reviewed.

Key words: wnt/β-catenin, satellite cells, muscle fiber types
