Abstract:

BACKGROUND: Human umbilical cord blood contains a large number of hemopoietic stem cells and mesenchymal stem cells. Neonate umbilical cord blood-derived stem cells show milder immunological rejection and lower immunogenicity than peripheral blood- and bone marrow-derived mesenchymal stem cells.
OBJECTIVE: To investigate the feasibility of umbilical cord blood-derived CD133 cells 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 cells were sorted by flow cytometry sorting technique and then transplanted into mouse models of gestational diabetes via the tail vein. At 7 days after cell 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 cells could be isolated from umbilical cord blood monocytes using flow cytometry sorting technique, with cell purity of (90.24±2.56)%. At 7 days after cell 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 (all P < 0.05). In addition, atrophy of pancreatic tissue and infiltration of inflammatory cells were reduced. These results show that umbilical cord blood-derived CD133 cell transplantation can improve the disease condition of gestational diabetes by repairing injured pancreatic tissue, decreasing insulin resistance index and improving pancreatic islet function.
