Tissue healing involves several stages, including inflammation, proliferation, and remodeling. During the proliferation phase, fibroblasts produce collagen and other extracellular matrix proteins to form a new tissue scaffold. Angiogenesis, the formation of new blood vessels, also occurs to supply the healing tissue with nutrients and oxygen. In the remodeling phase, the new tissue is reorganized and strengthened to restore its normal function. This process can result in scar formation if the damage is extensive.
