Wnt signaling is known to regulate the formation of the blood-brain barrier. Here Hübner et al. dissect the underlying mechanisms using high resolution live imaging in zebrafish, and find that Wnt regulates anastomosis of angiogenic sprouts in the brain by counteracting sphingosine-1-phosphate receptor signaling.
