Fig. 4.

A cartoon illustrating pathways involved in zebrafish embryonic angiogenesis. SHH is a master regulator of angiogenesis and it regulates VEGF/VEGFR2. Neuropilin as a co-receptor is important for VEGF-VEGFR2 interaction and signaling, and regulates Semaphorin-PlexinD1 signaling. VEGFR2 signaling leads to vessel sprouting, whereas PlexinD1 signaling restricts angiogenesis and regulates vessel patterning. VEGFR2 induces regulates Dll4/Notch signaling, which in turn determines vessel specification (EphB4 on vein and EphrinB2 on artery) and vessel stability through Nrarp.
