Fig. S3 tfap2a inhibits Fgf signaling in the otic vesicle.
(A-J): Cross-sections (dorsal up, medial left) passing through the otic vesicle just posterior to the utricle showing expression of etv4 (A-D), etv5b (E-H) and sprouty4 (I, J) in heat-shocked wild-type (A, E, I), hs:tfap2a (B, F, J), non-heat shocked wild-type (C,G) and tfap2a morphant (D,H) embryos at indicated time points. (K-P): Whole-mount images (dorsal up, anterior left) showing dorsolateral views of the otic vesicle (outlined) stained for etv5b expression in heat-shocked wild-type and hs:tfap2a embryos at indicated times.
