Axon guidance receptor expression in ECs Schematic representation of the four families of axon guidance cues and their receptors. Predominantly endothelial-expressed receptors are labeled in red, receptors with shared expression in the nervous and the vascular system in blue and molecules with no (known) expression in the vascular system in black. Note that in each axon guidance receptor family, at least one member is expressed in the vasculature. See text for details.
