Fig. S7 Expression of ptc1 and ptc2 in wild type and Ihha morphant larvae. (A–B) ptc1 expression was reduced in Ihha-MO larvae as compared to that in control. A notable reduction of expression was observable in the endoderm (white arrows) as well as in the brain region (black arrows). (C–D) Expression of ptc2 was also reduced in morphants as compared to control, although some expression remained in the brain (black arrow) and pharyngeal region (white arrows). Abbreviations: sb, swimbladder. Numbers represent anterior somites. Scale bars: 250 μm.
