Abstract

During the repair phase of wound healing, fibroblasts migrate to the site of injury where they proliferate and synthesize constituents of the extracellular matrix of connective tissue. Their activity is regulated by mediators originating from cells of the blood clotting and inflammatory stage such as platelet-derived growth factor, epidermal growth factor, transforming growth factor-beta and other cytokines. This communication shows that chemotactic migration of normal dermal fibroblasts is elicited by epidermal growth factor in vitro and that platelet-derived growth factor and transforming growth factor-beta can down-regulate this activity. This suggests that in vivo these growth factors are part of an intricate network which connects and coordinates proliferation, protein synthesis and chemotactic migration of fibroblasts.
