ABSTRACT

Enhancing skeletal muscle growth is crucial for the protability of animal agriculture and the meat industry. Effective enhancement of skeletal muscle growth depends on our understanding of the mechanisms controlling skeletal muscle growth. Skeletal muscle development can be separated into three stages: (1) embryonic, (2) fetal, and (3) postnatal. Myogenesis at the embryonic stage is characterized by the formation of primary muscle bers, secondary muscle bers are formed at the fetal stage, and postnatal myogenesis is mainly associated with the activation of satellite cells and their involvement in muscle growth and damage repair.
