BACKGROUND:Human umbilical cord blood contains a large number of hemopoietic stem cels and mesenchymal stem cels. Neonate umbilical cord blood-derived stem cels show milder immunological rejection and lower immunogenicity than peripheral blood- and bone marrow-derived mesenchymal stem cels. OBJECTIVE:To investigate the feasibility of umbilical cord blood-derived CD133 cels for treatment of gestational diabetes, so as to provide novel methods for clinical treatment of gestational diabetes. METHODS:Mouse models of gestational diabetes were established by high-fat and high-sugar diet feeding. Umbilical cord blood-derived CD133 cels were sorted by flow cytometry sorting technique and then transplanted into mouse models of gestational diabetesvia the tail vein. At 7 days after cel transplantation, serum levels of fasting blood glucose, fasting insulin, total cholesterol and triacylglycerol were measured and mouse pancreatic tissue injury and repair was observed by hematoxylin-esoin staining. Mouse insulin resistance index and pancreatic islet function were analyzed using the homeostatic model assessment. RESULTS AND CONCLUSION:Umbilical cord blood-derived CD133 cels could be isolated from umbilical cord blood monocytes using flow cytometry sorting technique, with cel purity of (90.24±2.56)%. At 7 days after cel transplantation, serum levels of fasting blood glucose, fasting insulin, total cholesterol and triacylglycerol were significantly decreased, insulin resistance index was significantly decreased, and pancreatic islet function was significantly improved in mouse models of gestational diabetes (alP < 0.05). In addition, atrophy of pancreatic tissue and infiltration of inflammatory cels were reduced. These results show that umbilical cord blood-derived CD133 cel transplantation can improve the disease condition of gestational diabetes by repairing injured pancreatic tissue, decreasing insulin resistance index and improving pancreatic islet function.
