    摘要:

    骨血管在骨生长、重塑和损伤修复中发挥重要作用,H型血管是一类同时高表达CD31与Emcn的骨血管亚型,具有显著的解剖特征与年龄依赖性减少特点,深度参与血管生成与骨形成之间的偶联。一些细胞因子如缺氧诱导因子1α、血管内皮生长因子A、血小板衍生生长因子BB、神经轴突导向因子3等可参与调控H型血管的生成,同时药物治疗、物理治疗和转移性肿瘤也能对H型血管产生影响。本文通过回顾近年文献,总结H型血管生成的分子机制与影响因素,以期为骨折不愈合、骨代谢异常等骨病的治疗提供新思考。

    Abstract:

    Blood vessels in bone tissue play an important role in bone growth, development, remodeling and injury repair. Type H vessels are a subtype of bone vessels with high expression of CD31 and Emcn, which have significant anatomical characteristics and age-dependent decline characteristics, and are deeply involved in the coupling between angiogenesis and bone formation. Some cellular molecules, such as hypoxia inducible factor-1, vascular endothelial growth factor-A, platelet derived growth factor-BB, and slit guidance ligand 3, are involved in regulating the formation of Type H vessels. Meanwhile, drugs therapy, physical therapy, and metastatic tumors can also affect Type H vessels. In this paper, the molecular mechanism and influencing factors of Type H vessels formation are summarized by reviewing the literature in recent years, in order to provide new thinking for the diagnosis and treatment of bone diseases such as fracture nonunion and abnormal bone metabolism.
