Fig. 5From: 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 signalingThe effect of hucMSCs on tubule formation of HUVECs. A Tube networks formation of HUVECs in the control, HG and MSC-CM groups (scale bar = 20 μm). B Nb nodes, Nb junctions, and total tubule length of tube networks in the control, HG and MSC-CM groups. Data were mean ± SD, *P < 0.05 versus control level, and #P < 0.05 versus model levelBack to article page
