摘要:

骨血管系统不仅为高代谢的骨细胞提供氧气与营养物质,也参与骨形成与骨再生过程。骨组织毛细血管可分为两种亚型,它们具有不同的形态和生理特点。内皮细胞与骨细胞通过多种信号通路沟通,血管形成与骨形成也具有协同作用。对骨血管结构及血管形成信号通路的探索有助于骨折愈合临床治疗的发展。

Abstract:

The vascular system in bone not only provides oxygen and nutrients to highly anabolic skeletal cells, but also participates in the process of bone formation and bone regeneration. Based on morphological and physiological characteristics, two subtypes of bone capillaries can be distinguished. Endothelial cells and osteoprogenitor cells influence each other by secreting specific growth factors, which have an important role in the coupling of angiogenesis and osteogenesis. A greater understanding of the architecture of the bone vasculature and the angiogenic response may contribute to enhanced bone regeneration.
