Insulin-producing cells from bone marrow stem cells versus injectable insulin for the treatment of rats with type I diabetes

in the of and development of cells. In the study to compare Insulin-producing cells from bone marrow stem cells with injectable insulin in rats with type I diabetes. For this purpose, 40 rats were divided into four groups: the control or healthy group, the diabetic control group, the group that received differentiated insulin-producing cells from bone marrow, and the group that received insulin treatment. To differentiate insulin-producing cells from bone marrow, the femoral bone marrow of rats was extracted using the flushing method. Differentiated cells were evaluated using dithizone-specific dye, anti-insulin-proinsulin antibodies, and anti-insulin beta receptors. Also, the expression of the pdx-I gene, as the specific gene of pancreatic cells, was examined by RT-PCR. The results showed that transplantation of insulin-producing cells could significantly increase blood insulin levels in diabetic rats. This increase intensified in the second stage of transplantation when more cells were injected into rats. Concerning decreasing blood sugar levels, differentiated cells were able to reduce blood sugar levels significantly. Even in the first stage of cell injection, in which the rats received a small number of cells, their blood sugar levels were controlled by these cells. As a result, the present study showed that repeated transplants of insulin-producing cells differentiated from bone marrow could decrease blood sugar and increase insulin levels.
