Key to wound healing is prescence of granulation tissue. Fibronectin is a very important proteoglycan and is involved in the healing of the wound. Fibronectin is an important adhesion agent and chemotactic agent, inviting fibroblast in helping healing process. The granulation tissue starts at day 3 and is on its prime by day 5.
