Mast cell activities during wound healing. Secretion of mediators by MCs affects several phases of wound healing.

MCs influence the remodeling phase and scar formation by secreting proteases that cleave extracellular matrix components and by producing a variety of mediators that stimulate fibroblasts (right side).
