Effect of MSCs on vascular endothelial growth factor (VEGF), C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), triglyceride, pancreatic beta cells and insulin resistance in Oobese Type 2 diabetic rat model Effect of MSCs on Vas

Aim to investigate the potential of SG followed by injection of MSCs in type 2 diabetic rats with obesity in improving IR. Methods This study used a pre and post-control group design with 24 rats divided into three groups: Control (C), SG, and SG + MSCs (SG+M). On day 10, the level of vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), triglyceride (TG), pancreatic beta cells, and homeostasis model assessment of IR (HOMA-IR) was evaluated using qRT-PCR, ELISA, and immunohistochemistry. Results A significant decrease of TNF-α (1.179 pg/mL), CRP(209 pg/mL), and TG levels (82,83  15,02pg/mL) in all treatment groups on day 10, in which SG + M group showed optimum inhibition was found (p < 0.05). This result was in line with the optimum increase of VEGF (8,1500 ± 2,47397) and pancreatic beta cell(10,1783±0,47) in SG + M group (p < 0.05). Moreover, our study also revealed the optimum decrease of HOMA-IR in SG+M group on day 10 (49,8233 ± 1,07303). Conclusion A combination of SG and MSCs can optimally improve insulin resistance by inhibiting TNF-α, CRP, and TG level and upregulating VEGF and pancreatic beta cell in an obese T2DM rat model.
