建立一个有功能的血管系统需要在整个胚胎发育过程中经历多个复杂的步骤,从内皮细胞(EC)规格到血管构型到静脉和动脉层次。在内皮细胞最初组装成索状结构网络后,血管扩张和重塑通过包括血管萌发、融合和修剪在内的形态发生事件迅速发生。此外,血管形态发生包括管腔形成的过程,这对于将脐带转变为可灌流的血管管至关重要。对小鼠、斑马鱼、青蛙和人类内皮细胞的研究已经开始概述管腔形成的细胞和分子要求。虽然管腔可以通过不同的机制产生,但包括转录因子、小GTP酶和黏附蛋白和极性蛋白在内的多个保守分子的协调参与仍然是一个基本原理,使我们更接近于更彻底地了解这一复杂的事件。
The establishment of a functional vascular system requires multiple complex steps throughout embryogenesis, from endothelial cell (EC) specification to vascular patterning into venous and arterial hierarchies. Following the initial assembly of ECs into a network of cord-like structures, vascular expansion and remodeling occur rapidly through morphogenetic events including vessel sprouting, fusion, and pruning. In addition, vascular morphogenesis encompasses the process of lumen formation, critical for the transformation of cords into perfusable vascular tubes. Studies in mouse, zebrafish, frog, and human endothelial cells have begun to outline the cellular and molecular requirements underlying lumen formation. Although the lumen can be generated through diverse mechanisms, the coordinated participation of multiple conserved molecules including transcription factors, small GTPases, and adhesion and polarity proteins remains a fundamental principle, leading us closer to a more thorough understanding of this complex event.
