Vascular permeability is an important aspect of maintaining vascular function,and vascular permeability is mainly affected by the connection between vascular endothelial cells and the function of peripheral blood vessels.The effects of vascular endothelial growth factor(VEGF) and pigment epithelium derived factor(PEDF) on vascular permeability are closely related to these factors,and they also have direct or indirect contact.This article will be on the relationship between VEGF and PEDF and vascular permeab...
