Making Split Decisions Development of the vertebrate vasculature has been thought to involve just two mechanisms of blood vessel formation. Herbert et al. (p. 294 ; see the Perspective by Benedito and Adams ) identified a third mechanism in zebrafish in which two distinct, unconnected vessels can be derived from a single precursor vessel. Several vascular endothelial growth factors and signaling pathways, including ephrin and notch signaling, coordinated the sorting and segregation of a mixture of arterial and venous-fated precursor cells into distinct arterial and venous vessels. These findings provide a mechanistic framework for how mixed populations of cells can coordinate their behavior to segregate and form distinct blood vessels.
