title: Wound healing: the role of growth factors.
abstract: Wound healing is a complex biological process that requires cellular interactions between a variety of cells, including fibroblasts, myofibroblasts, smooth muscle cells, endothelial cells, keratinocytes and immune cells. These interactions are mediated by numerous factors such as growth factors, hormones, blood components and second messengers. Several growth factors that are released at the wound site are presumed to be necessary for wound healing. These include epidermal growth factor (EGF), fibroblast growth factor (FGF), insulin-like growth factor (IGF), keratinocyte growth factor (KGF), platelet-derived growth factor (PDGF), transforming growth factor (TGF) and vascular endothelial growth factor (VEGF). The clinical use of growth factors to stimulate the healing of wounds is currently being investigated. Several growth factors, including PDGF, FGF-2, IGF and KGF, have been used in clinical trials, and PDGF is currently approved for use in human medicine.
