Abstract:

BACKGROUND: Studies have shown that under certain conditions stem cells can be induced to differentiate into vascular endothelial cells, promoting local angiogenesis, generating the new capillary network, and enriching the collateral circulation, so as to improve lower limb ischemia.
OBJECTIVE: To explore the effects of umbilical cord blood stem cell transplantation on endothelium-dependent vasodilation of type 2 diabetic patients with lower extremity vascular disease.
METHODS: Totally 100 type 2 diabetic patients with lower extremity vascular disease were enrolled and divided into two groups: experimental group (n=60) and control group (n=40). The experimental group adopted the intravenous injection of umbilical cord blood stem cells, while the control group was subject to normal saline infusion. After 4 weeks, basic indexes and endothelium-dependent vasodilation were compared between two groups. 
RESULTS AND CONCLUSION: In the experimental group, fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, cholesterol, triglyceride levels were significantly reduced (P < 0.05), while fasting insulin, 2-hour postprandial insulin, vascular endothelial dilation function were significantly increased after treatment (P < 0.05). In the control group, there were no differences in fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin, cholesterol, triglyceride levels before and after treatment (P > 0.05). These findings indicate that umbilical cord blood stem cell transplantation can improve the endothelial function and promote the collateral circulation in type 2 diabetic patients with vascular lesions of lower extremities, thereby to avoid the occurrence of diabetic foot.
