Abstract:

BACKGROUND: With the development of biochemistry and cell biology, fracture has being study deeper, blood supply has been known to be an important factor influencing the fracture healing. Endothelial progenitor cells with good ability of angiogenesis will have a good clinical prospect in fracture healing.

 
OBJECTIVE: To review the recent research of endothelial progenitor cells in fracture healing.
METHODS: A computer-based online search of CNKI, Wanfang, PubMed databases was performed to collect articles published between 1980 and 2014 with the key words “endothelial progenitor cell, fracture, neovascularization, angiogenesis” in Chinese and English. A total of 48 articles addressing endothelial progenitor cell for angiogenesis in fracture healing were included in result analysis.
RESULTS AND CONCLUSION: Increasing evidence has shown that endothelial progenitor cells have great ability of neovascularzition and angiogenesis. Endothelial progenitor cells used in tissue engineering scaffolds can promote the survival rate of scaffolds in vivo, which is appropriate to a great part of delayed union and nonunion patients. However, the large-scale treatment with endothelial progenitor cells still has many problems, such as isolation, culture and amplification of endothelial progenitor cells in vitro, the number of transplanted cells and selection of scaffolds for transplanted cells, which need further research.
