[The role of selected cell growth factors in the wound healing process].
Growth factors, naturally occurring proteins secreted by different cells or tissues, play very important role in accelerating the wound healing process. Growth factors are mainly released from macrophages, neutrophils, lymphocytes, platelets and fibroblasts and induce cells to migrate, divide or produce other factors required for wound healing. These factors bind to target cells via specific cell-surface receptors and may elicit inhibitory or stimulatory responses, depending on interactions with other factors and the cellular environment into which they are liberated. Systemic growth factors, such as growth hormone and local epidermal growth factor, fibroblast growth factor, platelet-derived growth factor, transforming growth factor i and insulin-like growth factor show to enhance wound healing. Growth factors stimulate fibroblasts proliferation and chemotaxis, collagen synthesis, reepithelialization and angiogenesis. Although growth factors are not widely available for clinical use, many are studied actively to determine their role in the acceleration of wound healing. Results of animal experiments and preliminary clinical trials demonstrate that specific uses growth factors may become the new mode of therapy in wound healing process.
