Acute stress induces tissue damage through excessive cellular apoptosis. In our study, the effects of sesamin on apoptosis and wound healing were investigated. The angiogenesis effect of sesamin was evaluated by the abilities of adherence, migration and tube formation in human umbilical vein endothelial cells (HUVECs). Our data demonstrated that treatment with sesamin dose-dependently promoted the proliferation, adherence, migration and enhanced their angiogenic ability in vitro. Moreover, the increased apoptosis in HUVECs, which stimulated by tert-butyl hydroperoxide (TBHP) was significantly attenuated by the sesamin treatment. Furthermore, we revealed that neogenesis of granulation tissue and deposition and remodeling of the collagen matrix were accelerated by the administration of sesamin in our in vivo study. These results confirm that sesamin accelerates wound healing at least partly through its antiapoptotic effects on endothelial cells at the injury site. Thus, sesamin represents a potential therapeutic medicine for vessel injury-related wounds. Sesamin accelerated wound healing in rats via increasing granulation thickness and collagen deposition.
