Angiogenesis is driven by the directed migration of tip endothelial cells towards hypoxic tissues. Here, Kim et al. show that the generation of reactive oxygen species in endothelial cells upon hypoxia activates MST1, which subsequently promotes the nuclear translocation of FOXO1, and thus activates a pro-migratory transcriptional programme in endothelial tip cells.
