Nerves and blood vessels often follow parallel trajectories as they course through the body to their distal targets. Proteins that regulate the process of axon guidance have likewise been shown to play a crucial role in blood vessel migration. With the recent description of the endothelial tip cell as an analog of the axonal growth cone, the nerve-vessel analogy seems complete. Notwithstanding these considerable similarities, one crucial difference remains between neural and vascular guidance. While a navigating axon is but a single cell, a sprouting vessel is composed of multiple cells that must be coordinately regulated. Recent studies of the D114-Notch1 signaling pathway have provided valuable insight into how the vasculature accomplishes this crucial task.
