血管内皮细胞在视网膜出芽式血管生成中的作用及其调控机制

Function of vascular endothelial cells in retinal budding angiogenesis and its regulatory mechanism

摘要:

出芽式血管生成是视网膜血管生成的主要方式之一，在视网膜正常发育和新生血管性眼病中发挥作用。血管内皮细胞结构和功能的完整性是确保出芽式血管生成的必要条件。血管内皮细胞具有多种亚型，每种细胞群均发挥不同的功能，在生理和病理状态下受到信号通路、代谢、免疫炎症和非编码RNA等多种因素调控。本文就血管内皮细胞在视网膜出芽式血管生成中的作用及其调控机制进行综述。

Abstract:

In the progress of retinal angiogenesis, sprouting angiogenesis plays an important role in retinal normal development and neovascular diseases. The structural and functional integrities of vascular endothelial cells are essential condition of sprouting angiogenesis. Vascular endothelial cells possess various subtypes, each of which plays a different role in sprouting angiogenesis. Many mechanisms participate in the regulation of endothelial cells under physiological and pathological conditions, such as biological signaling pathway, metabolism, immune inflammation and non-coding RNA. In this review, we provided a brief overview of the role and the related regulatory mechanisms of vascular endothelial cells in retinal sprouting angiogenesis.
