Neuronal sFlt1 and Vegfaa determine venous sprouting and spinal cord vascularization

Abstract

The generation of vasculature in organs is regulated by cross-talk between the developing tissue and specialized endothelial cells. Here, the authors show that vessel growth feeding the zebrafish spinal cord is coordinated by balancing neuron-derived pro-angiogenic ligand Vegfaa and its receptor, sFlt1.
