(A) Schematic of the construct used for endothelial-specific rescue experiments. (B, C) Brightfield images of 96 hpf alk5+/+ and alk5-/- larvae carrying the EC-specific alk5b rescue transgene (Tg). (D–F) Confocal images of the OFT in 72 hpf Tg(kdrl:EGFP) larvae, showing the morphological rescue in Tg(fli1a:alk5b-mScarlet) alk5-/- animals (F). Asterisk indicates the absence of the VA in alk5 mutants; dotted lines outline the OFT. (G) Percentage of OFT expansion in 78 hpf alk5+/+, alk5-/-, and Tg(fli1a:alk5b-mScarlet) alk5-/- animals. (H) Percentage of EdU+ ECs in 72 hpf alk5+/+, alk5-/-, and Tg(fli1a:alk5b-mScarlet) alk5-/- animals. (I–K) Confocal images of 75 hpf Tg(kdrl:EGFP) larvae immunostained for Eln2. Arrowheads, SMCs devoid of (white) or surrounded by (yellow) Eln2 immunostaining; I, n = 12; J, n = 13, K, n = 17. (G, H) Plot values represent means ± SD; p values from Kruskal-Wallis test, compared with the first column (alk5+/+). VA- ventral artery; Tg- Tg(fli1a:alk5b-mScarlet). Scale bars: (B, C) 200 μm; (D–F, I–K) 10 μm. See also Figure 5—figure supplement 1.
