Abstract

Mammalian skeletal muscles are derived from mesoderm segments flanking the embryonic midline. Upon receiving inductive cues from the adjacent neural tube, lateral plate mesoderm, and surface ectoderm, muscle precursors start to delaminate, migrate to their final destinations and proliferate. Muscle precursor cells become committed to the myogenic fate, become differentiated muscle cells, and fuse to form myofibers. Myofibers then fuse together to form the muscle groups. Muscle precursor cells have the ability to proliferate, and differentiate during development, while a subset remains capable of regeneration and repair of local injuries in adulthood. When the process of muscle development is perturbed such as in muscular dystrophies and injuries, ways to intervene and allow for proper muscle development or repair are the focus of regenerative medicine. Thus, understanding the developmental program of muscle at the genetic, cellular, and molecular levels has become a major focus of skeletal muscle regeneration research in the last few years.
