Fig. S2 (A) Confocal image time series of a single growing trunk ISV sprout in a Tg(fli1a:EGFP)^y1 embryo, showing dynamic changes in sprout morphology over time. (B) Confocal image of growing trunk ISV in a 28 hpf Tg(kdrl:mCherry-caax)^y171 embryo injected with a Tol2(fli1a:EGFP-F)^y288 transgene. The injected transgene mosaically marks subsets of endothelial cells, but it is not possible to determine whether contiguously labeled endothelium represents one cell or multiple adjacent cells. All images are lateral views with rostral to the left. Scale bars = 20 µm.
