Abstract :
Diabetes Mellitus is an autoimmune and chronic disorder that has spread rapidly all over the world due to lifestyle and obesity. In this study, we are trying to find an effective step in controlling diabetes by designing an engineered tissue and grafting it to different sites in the animal model. Uterine endometrial mesenchymal stem cells (EnMSCs) were prepared using the enzymatic extraction method and PAN nanofiber scaffold by electrospinning method. EnMSCs were cultured on the scaffold and transplanted into diabetic rats treated with streptozotocin. The engineered tissue was transplanted in one group peritoneally in the abdominal cavity and the other group subcutaneously. Also, in another group of rats, EnMSCs were injected through the tail. After transplantation, blood glucose, insulin, and weight of rats were measured. The findings of the present study showed that the method and area of stem cell transplantation play an important role in the control of diabetes. In the groups receiving EnMSCs, glucose concentration, blood insulin level, and body weight were improved compared to the control group. Compared to other groups, glucose concentration decreased significantly and blood insulin level and body weight increased significantly in rats receiving a peritoneal transplant. In the subcutaneous transplant group and the injection group, there was no significant difference in the investigated criteria. According to the results of this study, transplantation of EnMSCs using PAN scaffold in the peritoneal site can be suggested for the treatment of diabetes, although more studies are needed in this field to provide a complete treatment.
