kat2a and kat2b are broadly expressed throughout the head region during zebrafish development. (A–F) Whole-mount in situ hybridization (ISH) of kat2a and kat2b expression during zebrafish development. Wildtype zebrafish embryos express both kat2a and kat2b in the head region, including the brain, the branchial arches, and the eye. (A,D) Lateral views at 24 h post fertilization (hpf) of expression of kat2a and kat2b. (B,C) Lateral views of wildtype embryos at 40 hpf shows kat2a expression in the eye, the branchial arches, and the otic vesicle. (E,F) Dorsal view at 48 hpf shows kat2b expression in the eye, the branchial arches, and the hindbrain. Lateral views, anterior is to the left. Yellow rectangles in B and E represent the regions shown in C and F, respectively. e, eye; ba, branchial arches; hb, hindbrain; ov, otic vesicle. Scale bars represent 250 μm (A,D) and 100 μm (B,E).
