何时何地建立或破坏新的血管连接是理解引导血管模式的关键。VEGF-A刺激和Dll 4/Notch信号传导通过调节内皮尖端细胞形成来协同控制新连接的数量。在这里,我们发现Notch调节的锚蛋白重复序列蛋白(Nrarp)作为Notch和Lef 1依赖的Wnt信号在内皮细胞之间的分子连接,以控制小鼠和斑马鱼新血管连接的稳定性。Dll 4/Notch诱导的Nrarp表达通过与Lef 1相互作用限制Notch信号传导并促进内皮柄细胞中的Wnt/Ctnnb 1信号传导。BATgal报告基因表达证实了内皮柄细胞中的Wnt信号传导活性。离体,内皮细胞的组合Wnt 3a和Dll 4刺激增强了Wnt-报告子活性,其通过Nrarp的丧失而被废除。在体内,Nrarp、Lef 1或内皮Ctnnb 1的缺失导致血管退化。我们认为Notch和Wnt信号之间的平衡决定了是否建立或破坏新的血管连接。
When and where to make or break new blood vessel connections is the key to understanding guided vascular patterning. VEGF-A stimulation and Dll4/Notch signaling cooperatively control the number of new connections by regulating endothelial tip cell formation. Here, we show that the Notch-regulated ankyrin repeat protein (Nrarp) acts as a molecular link between Notch- and Lef1-dependent Wnt signaling in endothelial cells to control stability of new vessel connections in mouse and zebrafish. Dll4/Notch-induced expression of Nrarp limits Notch signaling and promotes Wnt/Ctnnb1 signaling in endothelial stalk cells through interactions with Lef1. BATgal-reporter expression confirms Wnt signaling activity in endothelial stalk cells. Ex vivo, combined Wnt3a and Dll4 stimulation of endothelial cells enhances Wnt-reporter activity, which is abrogated by loss of Nrarp. In vivo, loss of Nrarp, Lef1, or endothelial Ctnnb1 causes vessel regression. We suggest that the balance between Notch and Wnt signaling determines whether to make or break new vessel connections.
