Movie 13.

Lateral and medial proximal plexuses of an 18 dpf zebrafish 3D reconstructions of a confocal image stack of the fin of an 18 dpf (7.9 mm), Tg(kdrl:mcherry)^y206, Tg(mrc1a:egfp)^y251 double transgenic larva. The entire fin is initially shown, then only Tg(kdrl:mcherry)^y206-positive arteries (red), then only the proximal plexus region. 90-degree rotations of the proximal plexus show that it consists of two parallel plexuses, a lateral plexus (red) and a medial plexus (false-colored blue).
