Simultaneous Effect of Resistance Training and Endothelial Progenitor Cell Injection on the Expression of Vegf Angiogenic Factor and Its Relationship with Insulin Resistance in Diabetic Male Rats Induced By Stz

Exercise and the simultaneous use of progenitor cells is a new strategy aimed for reducing diabetic disorders. One of the known mechanisms is angiogenic disorders caused by diabetes. Therefore, the present study was performed to determine the simultaneous effect of resistance training with endothelial progenitor cell injection on the expression of angiogenic factors in the skeletal muscle of diabetic rats.

In this study, 30 rats were randomly divided into 5 groups: healthy, diabetic control (D) trained diabetic (DR), diabetic with endothelial progenitor cell injection (DI), diabetic trained with endothelial progenitor cell injection (DRI) were divided. VEGF protein expression was measured by Western blotting and insulin resistance index was measured by ELISA. The data were analyzed using two-factor analysis of variance test with SPSS software version 19 at a significance level of 5%.

In this study, 6 weeks of resistance training or progenitor cell injection caused a significant increase in VEGF and a significant decrease in insulin resistance index in diabetic rats. In the group that used simultaneous exercise and injection compared to the group with exercise and injection and these changes were significant in the group of simultaneous use of exercise and injection compared to the group of exercise with injection.

Based on the results of this study, it can be stated that resistance training or injection of endothelial progenitor cells can stimulate angiogenesis in skeletal muscle, also the simultaneous use of these two factors is a better way to increase angiogenesis in rats
