Abstract:
Bone defect repair is a complicated process of connective tissue repair under the control of various cytokines.It is the ample blood supply which is a necessary condition to promote regeneration of fracture,especially bone defect and nonunion.Hypoxia inducible factor 1 can induce formation of neovascularization with perfect physiological function in the lesion of bone defect by regulating various gene expression,and thus provide nutritional support and favorable conditions to metabolism for different cells in the process of osteogenic differentiation and osteogenic activity to promote the healing of fracture.Both gene therapy and using hypoxia inducible factor 1 directly have an ability to promote neovascularization in the lesion of fracture.It is a hotspot at present that hypoxia inducible factor 1 in the field of bone tissue engineering is used to treat bone defect.Hypoxia inducible factor 1 transgenic therapy needs further research in the repairing process of bone defect.
