Cranial vasculature enlargements seen in ccm3a/b morphants is not due to overproliferation of endothelial cells in the affected vessels. (A) Confocal z-stack projections of dorsal head vasculature in wildtype and ccm3a/b morphant embryos in the Tg(fli1:nlsEGFP) background at 54 hpf. (B) Endothelial cell nuclei were quantified in ccm3a/b morpholino injected (0.75 ng) and non-injected mesencephalic veins using the Tg(fli1:nlsEGFP) line. There was no statistically significant difference between the endothelial cell numbers in morphants compared to wildtype (p-value = 0.78). (C) Tg(kdrl:EGFP) embryos at 54 hpf were stained with mouse anti-ZO-1, and confocal images were analyzed for ZO-1 expression (red), and blood vessels (green). Cross-sections of the z-stack projections, as indicated by the white bars, revealed that wildtype mesencephalic veins (MsVs) were properly lumenized with strong ZO-1 expression at tight junctions along the circumference of the vessels. ccm3a/b morphant MsVs were enlarged, and in many instances failed to lumenize. ZO-1 expression in the morphants appeared disorganized and showed decreased co-localization with the vasculature (green).
