Retraction: Muscle‐derived Satellite Cells for Treating Type 1 Diabetes in Rats (Rattus norvegicus)

Diabetes mellitus(DM) is a complicated metabolic disease, with the fundamental treatment nowadays being diet control, insulin injections, slet or pancreas transplantation, which is limited because exogenous insulin injections fail to simulate normal insulin secretion in islet beta cells successfully and islet transplantation lacks organ donors. So far, stem cells with highly self-renewal and multi-directional differentiation potential have become a new hope for the treatment of diabetes. In this research, rat Muscle-derived satellite cells *MDSCs*were separated and cultivated in vitro and inducted into insulin-producing cells with observation and identification using dithizone staining and so on. T1D rat model was built with Streptozocin(STZ), then MDSCs and induced insulin-producing cells from MDSCs labeled by Dil were transplanted respectively. Transplantation of MDSCs (group 1) and the induced insulin-producing cells (group 2) into streptozotocin (STZ)-induced diabetic rats resulted in lower blood glucose, lower urine glucose, higher body weight, higher glucose tolerance and less water intake and urine output than control rats (P < 0.05). Among the male rats, the blood glucose levels of 50% of group 1 rats were <16.7 mmol/L, and 40% of group 2 rats yielded similar results (P < 0.01). Among the female rats, the blood glucose levels of 66.67% of group 1 rats were <16.7 mmol/L, and 33.33% of group 2 rats showed similar blood glucose levels (P < 0.01). Histological examination revealed that the transplanted cells reached the pancreas and repaired damaged tissues. The above research conclusions provide theoretical basis, cell selection and good prospect for the treatment of diabetes. This article is protected by copyright. All rights reserved.
