Abstract:Objective To investigate the therapeutic effects of human umbilical cord mesenchymal stem cells (UCMSCs) transplanted into a dog model of type 2 diabetes mellitus (T2DM) via the arterial intervention. Methods 24 Beagle dogs were randomly divided into UCMSCs treatment group (treatment group, n = 11), diabetic model control group (model group, n = 8) and normal control group (normal group, n = 5). Dogs in treatment and model control group were fed on high fat diet and intravenously injected with alloxan to establish T2DM models. Treatment group accepted insulin therapy and UCMSCs transplantation via arterial intervention. Model group only received insulin therapy, and normal group did not receive any treatment. Distribution of UCMSCs traced by CM-Dil was observed under fluorescence microscope. In addition, the three groups were compared with body mass, blood fat, fasting plasma glucose, insulin dosage, Area under the curve of C-peptide, insulin secretion index (HOMA-β), insulin resistance index (HOMA-IR) before and after therapy. Results The cells traced by CM-Dil mainly distributed in the pancreas and kidney. At 4 weeks after transplantation, fasting plasma glucose and insulin dosage were decreased gradually in treatment group , up to 12 weeks average daily insulin dose was declined from (27.94±1.86) U to (15.02±2.90) U. Compared with the model group, at 12 weeks triglyceride, low density lipoprotein cholesterol, HOMA-IR decreased (P < 0.05), under the curve of C-peptide, HOMA-β increased in treatment group (P < 0.05). Conclusion The method of translation of UCMSCs by artery intervention not only maximum guarantee the stem cells quantity into the pancreas , but also has great effects on reversing glucose and lipid metabolism disorder, recovering islet β cell function, decreasing insulin dosage, and relieving insulin resistance.
