文题释义:
骨生长因子:骨生长因子是通过自分泌或旁分泌方式作用于骨质的一组多肽,通过与靶细胞受体相结合,活化细胞内信号通路,抑制、增强细胞功能从而影响细胞迁移、增殖、合成、分化甚至细胞凋亡。同时靶细胞信号通路的活化进一步引起生长因子的表达来放大或减少细胞的整体反应形成一个负反馈循环。
受体酪氨酸激酶(receptor tyrosine kinase,RTKs):是最大的一类酶联受体,包括表皮生长因子受体、血小板生长因子受体、胰岛素样生长因子受体、神经生长因子受体等。它既是受体,又是酶,能够同配体结合,并将靶蛋白的酪氨酸残基磷酸化,与内信号蛋白结合后激活信号复合物,引起细胞内一系列生化反应,表现出如细胞增殖、分化等综合性应答。
 
摘要
背景:研究发现生物复合支架载体诱导骨生长因子在骨折局部的充分表达能够有效缩减骨折愈合的时间。
目的:综述国内外相关文献,总结骨生长因子调控骨折愈合机制及应用进展。
方法:中文以“骨生长因子、成纤维细胞生长因子、血小板衍生生长因子、转化生长因子β、骨形态发生蛋白、血管内皮生长因子、胰岛素样生长因子”检索CNKI、维普、万方数据库;英文以“BGF、FGF、PDGF、TGF-β、BMP、VEGF、IGF”为检索词检索PubMed数据库,纳入骨生长因子调控骨折愈合机制及其应用研究文章,排除重复及陈旧文献,共纳入文献58篇。
结果与结论:各类骨生长因子来源广泛,特点不一,都有各自的作用机制,通过旁分泌、自分泌等多种方式形成局部及系统的协同作用,与靶细胞受体相结合,活化细胞内信号通路,增强细胞功能从而影响细胞迁移、增殖、合成、分化甚至细胞凋亡,有效促进骨愈合、治疗骨缺损。但是骨生长因子具有半衰期短、蛋白易失活等缺陷,通过优化载体设计、递送方式和研发新型生物医学材料能够有效改善骨生长因子的这些缺点,更好地用于骨再生修复。

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.
