Abstract:

BACKGROUND: Studies have confirmed that umbilical cord blood stem cells can improve the neurological function after stroke, but the mechanism of umbilical cord blood stem cells in the treatment of stroke is unclear. 
OBJECTIVE: To review the effect and mechanism of umbilical cord blood stem cells in the treatment of stroke.
METHODS: The first author searched PubMed and CNKI databases for relevant articles published from January 2005 to December 2015 using key words of “umbilical cord blood stem cells, stroke” in English and Chinese, respectively.
RESULTS AND CONCLUSION: With the further research on the neural differentiation of umbilical cord blood stem cells, umbilical cord blood stem cells have become a hot research topic in the field of neural system disease therapy. At present, some experimental studies on cell transplantation for stroke have achieved ideal curative effects. However, the mechanism of umbilical cord blood stem cells in the treatment of stroke is not clear. Known therapeutic mechanisms include the recombination of blood vessels, nerve loops and other damage tissue structures, secretion of various nutritional factors to reduce endogenous apoptosis, promotion of endogenous blood vessels and nerve regeneration, etc. But the following problems need to be further studied, including whether the transplanted cells can be fully filled to replace necrotic nerve cells and promote recovery of nerve function; how these survived stem cells establish the neural connections; how these transplanted cells reduce the apoptosis and necrosis of the host cells to restore the cell function.
