Numerous studies have proposed the transplantation of mesenchymal stem cells (MSCs) in the treatment of typical type 2 diabetes mellitus (T2DM). We aimed to find a new strategy with MSC therapy at an early stage of T2DM to efficiently prevent the progressive deterioration of organic dysfunction. Using the high-fat-fed hyperinsulinemia rat model, we found that before the onset of typical T2DM, bone marrow-derived MSCs (BM-MSCs) significantly attenuated rising insulin with decline in glucose as well as restored lipometabolic disorder and liver dysfunction. BM-MSCs also favored the histological structure recovery and proliferative capacity of pancreatic islet cells. More importantly, BM-MSC administration successfully reversed the abnormal expression of insulin resistance-related proteins including GLUT4, phosphorylated insulin receptor substrate 1, and protein kinase Akt and proinflammatory cytokines IL-6 and TNFα in liver. These findings suggested that MSCs transplantation during hyperinsulinemia could prevent most potential risks of T2DM for patients.

Abstract Objective: The purpose of this study was to investigate the therapeutic effects of genetically modified mesenchymal stem cells (MSCs) in the treatment of type 2 diabetes mellitus (T2DM) in order to identify a new method for treating diabetes that differs from traditional medicine and to provide a new means by which to fundamentally improve or treat diabetes. Methods: MSCs derived from adipose tissue were modified to overexpress FGF21 and GLP1, which was achieved through lentiviral particle transduction. The cells were transplanted into BKS.Cg-Dock7m+/+Leprdb/Nju mice (T2DM mouse model). Injections of physiological saline (0.1 mL) and liraglutide (0.5 mg/kg) were used as negative and positive controls, respectively. ELISA or Western blotting were used for protein analysis, and quantitative real-time PCR was used for gene expression analysis. Results: Genetic modification had no effects on the morphology, differentiation ability, or immunophenotype of MSCs. Moreover, MSC-FGF21+GLP1 cells exhibited significantly increased secretion of FGF21 and GLP1. In the T2DM mouse model, the transplantation of MSC-FGF21+GLP1 cells ameliorated the changes in blood glucose and weight, promoted the secretion of insulin, enhanced the recovery of liver structures, and improved the profiles of lipids. Moreover, FGF21 and GLP1 exerted synergistic effects in the regulation of glucolipid metabolism by controlling the expression of insulin, srebp1 and srebp2. Conclusion: Stem cell treatment based on MSCs modified to overexpress the FGF21 and GLP1 genes is an effective approach for the treatment of T2DM.

Abundant evidence proves the therapeutic effect of adipose-derived mesenchymal stem cells (ADMSCs) in the treatment of diabetes mellitus. However, the problems have not been solved that viability of ADMSCs were inconsistent and the cells quickly undergo senescence after in vitro cell culture. In addition, the therapeutic effect of ADMSCs is still not satisfactory. In this study, melatonin (MLT) was added to canine ADMSC culture medium, and the treated cells were used to treat type 2 diabetes mellitus (T2DM). Our research reveals that adding MLT to ADMSC culture medium can promote the viability of ADMSCs. This effect depends on the binding of MLT and MLT receptors, which activates the transforming growth factor β (TGF-β) pathway and then changes the cell cycle of ADMSCs and improves the viability of ADMSCs. Since ADMSCs were found to be used to treat T2DM by anti-inflammatory and anti-endoplasmic reticulum (ER) stress capabilities, our data demonstrate that MLT augment several effects of ADMSCs in remission hyperglycemia, insulin resistance, and liver glycogen metabolism in T2DM patients. This suggest that ADMSCs and MLT-ADMSCs is safe and vabulable for pet clinic.

AbstractThe present study aimed to evaluate the diagnostic value of echocardiography in measuring the thickness of epicardial adipose tissue (EAT) of the patients of type 2 diabetes mellitus (T2DM) and its correlation with the intimal-medial thickness of the carotid artery (cIMT) to investigate the relationship between EAT and cIMT. 68 patients of T2DM were enrolled and were divided into 2 groups: group of T2DM with duration≤10 years (35 cases) and group of T2DM with duration>10 years (33 cases). And 30 healthy subjects were enrolled as the control group. The thickness of EAT and cIMT were measured by echocardiography and high-frequency ultrasonography. The thickness of EAT and IMT of the carotid artery of 2 type 2 diabetic groups (duration≤10 years and>10 years) were significantly higher than that of the control group (all p<0.05), and the thickness of EAT and cIMT of the group of T2DM with duration>10 years were significantly higher than that of the group of T2DM with duration≤10 years (p<0.05). In univariate analysis, the thickness of EAT was positively and significantly associated with age (r=0.412, p<0.05), BMI (r=0.566, p<0.05), waist circumference (r=0.475, p<0.05), LDL (r=0.425, p<0.05), TG (r=0.496, p<0.05), duration of diabetes (r=0.384, p<0.05) and cIMT (r=0.456, p<0.05). In multiple stepwise regression analyses, age, BMI and IMT of carotid artery were appeared to be significantly associated with EAT (p<0.05 for all). In conclusion, routine screening of EAT and cIMT by ultrasonography in type 2 diabetic patients helps us to predict cardiovascular risks and prevent further development of cardiovascular complications.
