Figure 1—figure supplement 2. Trunk vascular patterning and vascular gene expression in FACS-sorted endothelial cells from transgenic zebrafish.

(a) Confocal images of the vasculature in the mid-trunk of a five dpf Tg(mrc1a:eGFP)y251, Tg(kdrl:mCherry)y171 double-transgenic animal with mCherry positive arterial blood vessels (red), EGFP positive lymphatic vessels (green), and mCherry and EGFP double positive venous blood vessels (yellow). The different vessels are labeled: DA, dorsal aorta; DLLV, dorsal longitudinal lymphatic vessel; DLAV, dorsal longitudinal anastomotic vessel; ISLV: intersegmental lymphatic vessel; aISV: arterial intersegmental vessel; vISV: venous intersegmental vessel; PCV, posterior cardinal vein; PL, parachordal line; TD, thoracic duct; CCL, collateral cardinal lymphatics; VTA, vertebral artery. (b) Confocal image from panel a with lymphatic vessels pseudocolored in green and other vessels in gray, for easier visualization of the lymphatic network. (c) Quantitative TaqMan RT-PCR measurement of the relative expression of lymphatic endothelial cell (LEC) genes lyve1b and prox1a in FACS-sorted zebrafish endothelial cell populations. Expression is normalized to the arterial (mCherry-positive) endothelial cell population. (d) Quantitative TaqMan RT-PCR measurement of the relative expression of blood endothelial cell (BEC) genes kdrl and cdh5 in FACS-sorted zebrafish endothelial cell populations. Expression is normalized to the lymphatic (EGFP-positive) endothelial cell population. Scale bars = 100 µm (a,b). Biological duplicates were analyzed. All graphs are analyzed by t-test and the mean ± SD is shown.
