Fig. 4 PDGFR inhibition blocked ISV formation and extension.

kdrl:GFP embryos were treated at the shield stage (6 hpf) with DMSO alone, 0.1 µM PDGFR tyrosine kinase inhibitor V (inhV), or 0.25 µM inhV. Inhibition of PDGFRs resulted in a decrease in the number of angiogenic sprouts (asterisks in A) in the tail at 24 hpf (B) and a decrease in the number of complete ISVs (arrowheads in A) at 48 hpf (A and C) and 72 hpf (A and D). The morphology for all treatments at 24 hpf was normal (E). Embryos treated with 0.25 µM inhV began to show edema (arrowhead in F) and pooling of blood (arrow in F) at 48 hpf. Angiography at 72 hpf showed a decrease in blood circulation through the ISVs in embryos treated with inhV (G). *** indicates p<0.001. All data represent the mean +/- standard error.
