Abstract:

BACKGROUND: Stem cells under the certain condition can be induced to differentiate into vascular endothelial cells, to promote local angiogenesis and generate new capillary network and establish abundant collateral circulation, in order to achieve the purpose of improvement and treatment of lower limb ischemia.
OBJECTIVE: To review the pathogenesis of diabetic lower extremity vascular lesions, and the basic and clinical development of autologous peripheral blood stem cell transplantation, umbilical cord blood stem cell transplantation, and stem cell transplantation combined with cytokines for the treatment of diabetic lower extremity vascular lesions.
METHODS: A computer-based online search was performed in the PubMed database for relevant literatures published from 1983 to 2014. The keywords were “stem cells; stem cell transplantation; cord blood stem cell transplantation; diabetic angiopathies”.
RESULTS AND CONCLUSION: The pathogenesis of diabetic lower extremity vascular lesions may be associated with dysimmunity-induced inflammation. It is lack of effective treatment methods. Stem cell transplantation in animal models and clinical treatment of diabetes complications has obtained certain achievements. Embryonic stem cells, mesenchymal stem cells and endothelial progenitor cells are widely used, and the their mechanism underlying treatment of diabetic lower extremity vascular lesions is mainly related to their participation in new vessel formation, starting and secreting factors, immune regulation, and stem cell proliferation and differentiation ability. Currently, the basic research is mainly limited to simple stem cell transplantation and stem cell transplantation combined with gene therapy. Compared with peripheral blood stem cell transplantation, autologous bone marrow stem cell transplantation is preferred because of more primitive cells, simpler operation, and lower cost. Studies have confirmed that cytokines secreted from stem cells are not enough to promote angiogenesis, but stimulate the skeletal muscle cells to secrete enough factors for promoting angiogenesis. The current clinical application of stem cells has a lot of problems to be solved.
