nkx3.2 mutant zebrafish develop axial skeletal abnormalities. (A,E) µCT imaging of 60?dpf wild types (A,A?) and nkx3.2ua5011/ua5011 mutants (E,E?) shown with gradient 3D rendering in sagittal (A,E) and dorsal (A?,E?) views. (B-D,F-H) Magnifications of three spinal regions: anterior vertebrae (red box, inclusive of the occiput and Weberian apparatus: B,B?,F,F?), precaudal vertebrae with rib articulations (tan box, white arrows indicate corresponding left and right ribs: C,C?,G,G?), and caudal fin vertebrae (blue box, pink arrow indicates caudal-most vertebra: D,D?,H,H?) shown in 3D (B,C,D,F,G,H) and 2D (B?,C?,D?,F?,G?,H?) slice. Scale bars: 1?mm (A,A?); 0.61?mm (E,E?).
