Robo4 expression in emerging blood vessels can neutralize signaling through the angiogenic factor vascular endothelial growth factor (VEGF) and maintain vessel integrity. The findings could lead to new therapeutic targets for angiogenesis and vascular leakage (pages 448–453).

In recent years, it has emerged that guidance cues responsible for neuronal development also have crucial roles in vessel formation and maturity. Many researchers have drawn a comparison between an actively developing axonal sprout and a newly forming blood vessel, as both migrate, elongate or retract in response to cues from surrounding tissues and matrix.
