Vessels and Nerves: Marching to the Same Tune

Abstract

The patterning of the nervous system is achieved through coordinated action of a variety of repulsive or attractive neuronal guidance factors that direct the growth of growing axons to specific pathways. Recent studies suggest that the same or similar sets of factors also guide migration of endothelial cells, helping to direct the stereotypical embryonic patterning of the developing vertebrate vascular system.
