Fig. 11From: Human umbilical cord-derived mesenchymal stem cells not only ameliorate blood glucose but also protect vascular endothelium from diabetic damage through a paracrine mechanism mediated by MAPK/ERK signalingMechanism of hucMSCs on modifying negative impact of glucose on endothelial cell injury. The red arrows represent the high glucose-induced injury process and the green arrows represent the MSCs intervention processBack to article page
