Fig. 1. Whole mount in situ hybridization showing spatial and temporal expression of tweety homologs in developing X. laevis embryos. Row 1 and 2: dorsal views. Rows 3, 4, 5: both lateral (top embryo, with dorsal side on top) and dorsal (bottom embryo) views. Anterior is oriented to the right for all embryos. Row 6: close up of anterior part of the embryo, with a lateral view (dorsal side on top) and a dorsal view (with anterior directed upwards). (A, G, M) Stages 19–20 (late neurula). (B, H, N) Stages 22–23 (early tailbud). (C, I, O) Stages 25–26 (mid-tailbud). (D, J, P) Stages 29–31 (late tailbud). (E, K, Q) Stages 34–35 (swimming tadpole). (F, L, R) Stages 34–35 (swimming tadpole, close up). (A–F) Ttyh1 expression. (G–L) Ttyh2 expression. (M–R) Ttyh3 expression. Arrowheads indicate regions of expression. (fb, forebrain; e, eye; hb, hindbrain; mb, midbrain; ot, otic vesicle; pa, pharyngeal arches; sc, spinal cord; nt, neural tube; so, somites; Roman numerals: cranial ganglia.) Scale bars = 1.0 mm.
