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 with the initial inflammatory response
  2. Regeneration phase, phagocytosis of damaged tissue, followed by myofibers regeneration, leading to satellite cell activation.
  3. Remodelling phase, maturation of regenerated myofibers with recovery of muscle functional capacity and also fibrosis and scar tissue formation.[1]

Physiopedia has many great muscle repair related pages. Take a look at the following links to get a deeper understanding.
