cDNA Muscle

Skeletal muscle cells, one of the largest cell types in the body, are multinucleated cells formed by the fusion of myoblasts. Skeletal muscle regeneration is a complex process. When skeletal muscle is injured, quiescent resident myoblasts called satellite cells are activated to proliferate, migrate, and differentiate. Various cellular signaling pathways, such as phosphatidylinositol 3-kinase, calcineurin, Janus kinase 2/signal transducer and activator of transcription 3 (STAT3), and mitogen-activated protein kinase (MAPK) have been suggested to play an important role in skeletal muscle growth. Insulin-stimulated glucose transport in cultured human skeletal muscle cells is mediated by GLUT4 and heparan sulfate proteoglycan is involved in skeletal muscle differentiation. The fusion of mononucleated cells to form multinucleated myotubes is a central event in skeletal muscle development. Controlling the onset and progression of this process is a complex set of interactions between myoblasts and their environment. Skeletal muscle cell culture is a useful model for studying the process of cell differentiation.
