Fig. 6 fgf24 is required for epibranchial development. (A, E) Expression of pax8 at 11 hpf in a control embryo (A) and fgf24 morphant (E). (B, F) Expression of sox3 at 14 hpf in a control embryo (B) and fgf24 morphant (F). White arrows indicate the lateral edges of the otic domain and black arrows indicate the lateral edges of the epibranchial domain. (C, G) Two color in situ hybridization showing pax2a (red) and foxi1 (blue) in a control embryo (C) and fgf24 morphant (G) at 14 hpf. Positions of otic placodes (op) are indicated. (D, H) Expression of phox2a at 30 hpf in a control embryo (D) and fgf24 morphant (H). Positions of the facial ganglion (f), glossopharyngeal ganglion (g) and vagal ganglia (v1 and v2) are indicated. Images show dorsolateral views with anterior to the left (A, D, E, H); dorsal views with anterior to the left and dorsal to the top (B, C, F, G).
