Figure Caption/Comments:

Fig. 1 Vasculature of the zebrafish caudal fin. TG(fli1:EGFP)y1 fish express EGFP in blood vessel endothelial cells. (A) Bright field image of the ventral half of the caudal fin of an adult TG(fli1:EGFP)y1 fish and (B) epiflourescence image of the same fin, revealing the vasculature. (Inset) Higher magnification of the distal end of a fin ray (boxed region) shows that each fin ray is associated with one artery (red arrow) in the center of the ray and two veins (red arrows) adjacent to the bony ray. (C) High magnification image shows the intervessel commissures within the same ray (white arrow), which connect artery to vein as well as vein to vein. The interray vessels (white arrowhead) connect vein to vein of adjacent rays. (D, E) Cross-section through a fin ray shows the artery in the center of intraray mesenchyme (red arrow), while the veins are in interray mesenchyme adjacent to the bony rays (yellow arrows). Intervessel commissures (white arrows) and interray vessels (white arrowheads) are also visible in this section. Explanatory diagram is shown in (E). Scale bars, 200 μm in (A, B, C), 20 μm in (D).
