Blocking the function of MEK with specific inhibitor U0126 or PD98059 treatment resulted in sprouting angiogenesis defects. A. Confocal images of ISVs morphology in 30 hpf Tg(kdrl:EGFP) transgenic embryos treated with DMSO, U0126 or PD98059. B. Confocal images of 30hpf Tg(fli1a:EGFP) transgenic embryos treated with DMSO, U0126 or PD98059. C. The statistics of ISV length in embryos treated with DMSO, U0126 or PD98059. One-Way ANOVA; ***,P<0.001. D. Quantification of ECs nuclei number in ISV. Measurements were made from three adjacent ISVs (over yolk) per embryo from 3 independent experiments. One-Way ANOVA; ***, P<0.001.
