Figure 7From: Nitric oxide and superoxide dismutase modulate endothelial progenitor cell function in type 2 diabetes mellitusInsulin and SOD effects on glucose-stressed EPC cultures. Glucose-stressed EPCs were treated with insulin, SOD, or both. (a) Effect of insulin, SOD, or both on NO production. (b) Effect of insulin, SOD, or both on O2- generation. (c) Effect of insulin, SOD, or both on the number of EPC colonies. Data are expressed as mean percentage ± SEM or mean number ± SEM of triplicate measurements in each sample from four independent tests. *P < 0.05, **P < 0.001, ***P < 0.001 vs. glucose-stressed EPCs. NS represents non-significant.Back to article page
