| Abstract | ||||
| Background: Diabetic cardiomyopathy (DCM) is a common condition that is associated with morbidity and mortality. With the medical advancement in cell treatment, stem cell therapy has a potential therapeutic strategy for DCM. Objectives: We aim to evaluate the possible therapeutic effects of Mesenchymal stem cells (MSCs) versus melatonin (MLT) preconditioned-MSCs in induced diabetic cardiomyopathy in rats. Materials and Methods: Forty-five male adult albino rats were divided into four groups. Group I: Control group. Group < br />II: Diabetic group: Rats received single intraperitoneal injection of streptozotocin STZ (50 mg/kg body weight). Group < br />III: DC treated with MSCs. Group IV: DC treated with MLT preconditioned-MSCs. Histological, ultrastructural and immunohistochemical studies were performed on left ventricle myocardium. We also estimated the survival of MLTpreconditioned MSCs in vitro. Bcl-2, Casp-3, interleukin 1 (IL-1), and interleukin 10 (IL-10) expression were measured using real-time PCR in tissue homogenates. Results: Our findings revealed a significant increase in immunohistochemical expression of apoptotic markers in the diabetic group, as well as a disruption of the normal cardiac histological ultrastructure. Melatonin improved MSCs survival in vitro and altered apoptotic markers. In addition, the melatonin-preconditioned MSC group showed a significant increase in B-cell lymphoma 2 (Bcl-2) mRNA expression and a significant decrease in Casp-3. Enhanced immunomodulatory behavior was obvious by a significant attrition of the mRNA expression of IL-1β (inflammatory-agonist) and a significant altitude of IL-10 (inflammatory-antagonist). Conclusion: The melatonin-preconditioning of MSCs enhance their survival and immunomodulatory activities and precisely restored cardiac histology. Thus, it unveils an encouraging interference of DC. | ||||
