Introduction[edit | edit source]

Myogenesis Schematic of satellite cell myogenesis and markers typical of each stage.jpg

Skeletal muscle repair requires the activation of satellite cells, which are the residential muscle stem cells. The repair/regeneration is a highly coordinated process, involving cell-cell, cell matrix and extracellular matrix interactions. Immune, fibrotic, vascular and myogenic cells all play a role in the three phases of muscle repair/ regeneration. These phases

  1. Destruction phase : distinguished by rupture and necrosis of the myofibers, formation of a hematoma and an critical inflammatory reaction.
  2. Regeneration phase: phagocytosis of damaged tissue preceding myofibers regeneration, leading to satellite cell activation.
  3. Remodelling phase: maturation of regenerated myofibers with recovery of muscle functional capacity and fibrosis and scar tissue formation.[1]
