Myotrophic Factors

Meaning

Myotrophic Factors are a class of signaling molecules, primarily peptides and proteins, that exert a direct or indirect effect on muscle tissue, promoting muscle cell growth (hypertrophy), differentiation, repair, and essential maintenance. These factors are absolutely essential for preserving muscle mass and strength, which are critical determinants of metabolic health, functional independence, and physical longevity. They act locally and systemically to govern skeletal muscle plasticity.
