ABSTRACT
Axonal guidance and vascular patterning share several guidance cues, including proteins of the netrin family. We demonstrate that netrins stimulate the proliferation, migration and tube formation of human endothelial cells in vitro, and that this stimulation is independent of known netrin receptors. Knockdown of netrin1a mRNA in zebrafish inhibits vascular sprouting, implying a pro-angiogenic role for netrins during vertebrate development. We also show that netrins accelerate neovascularization in an in vivo model of ischemia and that they reverse neuropathy and vasculopathy in a diabetic murine model. We propose that the attractive vascular and neural guidance functions of netrins offer a unique therapeutic potential.
