Decreased EC Proliferation in Nrarp-/- Mouse and in nrarp-a and nrarp-b Morphants (A–D) Control, nrarp-a and -b MO-injected Tg(fli1:EGFP)y1 zebrafish embryos were exposed to BrdU (red) from 19 to 48 hpf. Circles highlight ECs nuclei along ISVs. Arrows indicate BrdU-positive ECs. (D) Quantification of BrdU-positive ECs in ISVs. Error bars indicate SEM. Control, n = 8 (31 ISVs); nrarp-a, n = 6 (47 ISVs); nrarp-b, n = 14 (66 ISVs). (E) Decrease in EC number in ISVs of nrarp-a and -b morphants. Bar graph shows the percentage of ISVs containing x number of endothelial nuclei per ISV at 48 hpf. Control MO, n = 17; nrarp-a MO, n = 16; nrarp-b MO, n = 21. Eight ISVs/embryo were analyzed. (F–I) 3 hr BrdU incorporation assay in P5 mice. Bar graph shows number of proliferated ECs in 10,000μm3 retinal vessels (F). *, p = 0.0328. Nrarp+/+, n = 17, Nrarp+/-, n = 8; Nrarp-/-, n = 14 images. Data show mean ± SEM. (G–I) Circles highlight BrdU-positive ECs in Nrarp+/+, Nrarp+/-, and Nrarp-/- retinas stained with Isolectin-B4 (green) and BrdU (red). |
