Cutaneus wound healing.
Keywords:
wound, scar, inflammation, cell proliferationAbstract
The mechanisms of wound healing come into function after an injury that alters the skin surface continuity. Three phases have been identified in the process: inflammatory, proliferative and tissue remodeling. In the inflammatory phase there is local cell infiltration, release of compounds transported by blood and activation of the coagulation system. In the proliferative phase there is formation of new tissue, due to cell growth and migration, and the participation of diverse adherence molecules. Tissue remodeling corresponds to the last phase, in which a stable tissue develops, similar to the one previously present before the injury, known as scar. The participation of growth factors, cytokines and diverse blood components are fundamental for the functional restoration of the affected area.
