Effect of Electrospun Nanofibers on Diabetic Wound Healing and Epidermal Growth Factor

Abstract

Diabetic wound, a common complication in patients with diabetes, is difficult to treat because of the long-term consequences of accumulating advanced glycation end products and high glucose levels. Moreover, wound infections occur frequently in diabetes; therefore, developing effective treatments is of great significance for healing diabetic wounds. Electrospun nanofibers have played a favorable role in wound healing, but the efficacy in diabetes is yet to be investigated. This study used mouse models of DW in order to determine the effect of electrospun nanofibers on wound healing. It turned out that electrospun nanofibers increased the healing rate in mice and inhibited levels of inflammatory cytokines, as well as activated epidermal growth factor (EGF). In vitro experiments revealed that the migration and proliferation of human umbilical vein endothelial cells (HUVECs) were enhanced after the intervention. Overall, electrospun nanofibers can improve the healing of diabetic wounds significantly.
