Gar CNS12 drives GFP expression in the pectoral fin of zebrafish. Brightfield (A, D, and G) and fluorescent (B, E, and H) images of gar CNS12 transgenic zebrafish. Lateral views are in A−C and dorsal views are in D−I. GFP expression is found in the dorsal part of the eye and pectoral fin field at 24 hpf (A, B, D, and E), and in the common cardinal vein (arrowhead) and pectoral fin bud at 36 hpf (G and H). Dotted lines outline the pectoral fin. Zebrafish tbx5a in situ hybridization at 24 hpf (C and F) and at 36 hpf (I). (Scale bars: 200 μm.)
