Fig. 3 In situ hybridization of fgfr2 gene expression. In situ hybridization of fgfr2 gene expression at 24 hpf (A–D), 36 hpf (E–H), 48 hpf (I–L), 60 hpf (M–P), and 72 hpf (Q–T). Lateral views (A, E, I, M, Q) with anterior to the left, dorsal at the top, dorsal views (B, F, J, N, R) with anterior to the left, rostral transverse brain sections (C, G, K, O, S), and caudal transverse brain sections (D, H, L, P, T). Dotted lines indicate approximate orientation of imaged sections. Solid arrowheads indicate the location of the midbrain–hindbrain boundary. Labels point to expression in the cerebellar plate (CeP), diencephalon (Di), dorsal forebrain (DFrb), dorsal midbrain (DMB), dorsal thalamus (DT), fin bud (FB), forebrain (FrB), forebrain ventricular zone (FrVe), hindbrain (HB), inner ear (E), jaw (J), lens (L), medulla oblongata (MO), midbrain (MB), otic placode (OP), periocular mesenchyme (POM), pharyngeal arches (PA), pharynx (P), rhombomere boundaries (RhB), and ventricle (Ve). In panels K and S, the asterisk draws attention to expression surrounding the lens.
