EGFL7 affects the migration of epidermal stem cells in refractory diabetic wounds by regulating Notch signaling pathway
Abstract
Aim: This study aimed to explore the role of EGFL7 in the healing process of refractory diabetic wounds. Methods: Epidermal stem cells (ESCs) were isolated from healthy mice and diabetic mice, identified by immunofluorescence, transfected with EGFL7 overexpression and silencing lentiviral vectors, and treated with Notch pathway inhibitor (DAPT). Results: SiEGFL7 significantly inhibited the proliferation, invasion and migration of ESCs of healthy mice. DAPT prominently inhibited the expressions of Notch1, Notch2, Hes1 and Jag1 in ESCs of healthy mice induced by overexpressed EGFL7. Overexpressed EGFL7 promoted wound healing in diabetic mice with refractory wounds. Conclusion: EGFL7 affects the proliferation and migration of ESCs in refractory diabetic wounds by regulating the Notch signaling pathway.
Plain language summary
EGFL7 silencing inhibited the proliferation, invasion and migration of ESCs of healthy mice, which was reversed by Notch signaling inhibition. Overexpressed EGFL7 promoted wound healing in diabetic mice with refractory wounds, providing a promising potential for the treatment of diabetic wound.
