Fig. 1 Histological analyses of the dorsal aorta and posterior cardinal vein of 3 months old zebrafish. (a–d) Toluidine blue-stained transverse sections of the trunk vasculature showing the dorsal aorta (DA) and posterior cardinal vein (PCV). A thick layer (arrows in (b and c)) of vascular SMCs (vaSMCs) is present around the DA but not the PCV, where single vaSMCs (arrow in (d)) are interspersed along the circumference of the PCV. Scale bars, 100 μm. *Peri-aortic melanocytes. Sections are at the level of the 10th somite.
