Abstract:

BACKGROUND: Under certain conditions, stem cells can be induced to differentiate into vascular endothelial cells, which can promote the angiogenesis of ischemic lower limbs and the establishment of effective circulation and improve distal blood supply of the ischemic limbs.

OBJECTIVE: To review the biological characteristics and pro-angiogenesis mechanism of umbilical cord mesenchymal stem cells and to investigate the current status of umbilical cord mesenchymal stem cells in the repair of neuropathy and chronic wounds.

METHODS: PubMed, VIP and Wanfang databases were searched for relevant articles published from 2000 to 2015 using the keywords of “stem cells transplantation, umbilical cord mesenchymal stem cell, diabetic angiopathies” in English and Chinese, respectively.

RESULTS AND CONCLUSION: Compared with peripheral blood stem cells and bone marrow mesenchymal stem cells, umbilical cord mesenchymal stem cells are characterized as more widespread sources, easy collection, stronger amplification ability, no immunogenicity, and no ethical controversy, which have become ideal target and seed cells for pro-angiogenesis and gene therapy in ischemic diseases. Umbilical cord mesenchymal stem cells can differentiate into vascular endothelial cells and fibroblasts involved in wound healing. In addition, these cells can promote the production and expression of neurotrophic factors, promote nerve regeneration in ischemic tissues, and participate in tissue repair and accelerate healing of ulcers by paracrine and autocrine cytokines, anti-inflammation and immunomodulation. Therefore, umbilical cord mesenchymal stem cells have a broad prospect in the improvement of diabetic lower limb ischemia, repair of diabetic peripheral neuropathy and promotion of chronic ulcer healing. Compared with stem cell transplantation alone, umbilical cord mesenchymal stem cells transplantation combined with gene therapy can further enhance cell survival and pro-angiogenesis.
