RESUMO
The role ofepidermal growth factor (EGF) has been extensively investigated in normal and pathological wound healing. It is implicated in keratinocyte migration, fibroblast function and the formation of granulation tissue. Since the discovery of EGF, the first growth factor to be isolated, over 45 years ago, growth factor therapy has progressed into clinical practice in the treatment ofwounds. The investigation EGF in wound healing has progressed from the treatment of acute wounds, to its limited effect in chronic wounds. EGF is readily degraded in the chronic wound environment, but with the recent focus of research in new drug delivery systems that are able to protect and stabilise the protein, the potential healing effects of EGF are at the forefront of research. In this review, the history of EGF and wound healing research is considered, as are current and future therapeutic options.
