Fig. S3 Whole-mount in situ hybridization of barx2 expression. (A) Dorsal view, anterior is to the left. (B, D, H) Lateral views, anterior to the left, (C) dorsal view; (E) ventral view; (C and E) anterior is to the top. (F) Lateral oblique view. (F inset) Sagittal section. (G) Coronal section. (A, B) Black arrowheads indicate bilateral sites of expression in the proximal aspect of the fin bud primordia. ae, aboral epithelium; bc, buccal cavity; e, eye; f, fin; fb, fin bud; h, hyoid arch; oe, oral epithelium; ole, olfactory bulb epithelium; ov, otic vesicle; m, mandibular arch.
