Abstract:

BACKGROUND: Biocomposite vector inducing the expression of bone growth factors in the fracture parts can effectively shorten the fracture healing time.

OBJECTIVE: To review the related literatures and to summarize the mechanism and application progress of bone growth factors regulating fracture healing.
METHODS: CNKI, VIP, WanFang and PubMed databases were retrieved with the keywords of “BGF, FGF, PDGF, TGF-β, BMP, VEGF, IGF” in English and Chinese, respectively. The articles concerning mechanism and application of bone growth factors regulating fracture healing were included, the repetitive studies were excluded, and finally 58 eligible articles were enrolled.
RESULTS AND CONCLUSION: Different kinds of bone growth factors are originated from different tissues, and have their own characteristics and action mechanisms. They produce local and systematic synergistic effect by paracrine and autocrine, and bind to the receptors in target cells, further activating the signaling pathways, promoting cell functions, thus affecting cell migration, proliferation, production, differentiation even apoptosis. Therefore, bone growth factors can effectively promote bone healing and treat bone defects. But bone growth factors exhibit shortcomings such as short half-life period and protein inactivation. Optimizing the design and delivery method as well as developing novel biomaterials to effectively overcome all above problems can contribute to bone regeneration and repair.
