Figure Caption

Figure 7 Fgf and lactate are required together for full activation of early otic genes.

(A–D) Dorsolateral view of the otic vesicle (outlined) showing expression of etv5b at 18 hpf in wild-type embryos or hs:dnfgfr1/+ transgenic embryos with or without exogenous 6.7 mM lactate added at 14 hpf, as indicated. Embryos were heat shocked at 39°C for 30 min beginning at 16 hpf. (E–H) Dorsal view (anterior to the top) of the hindbrain and otic region showing expression of the otic domain of pax5 (black arrows) in embryos with the indicated genotypes. Embryos were heat shocked at 37°C for 30 min beginning at 16 hpf. (I) A model for how lactate and Fgf signaling converge on MAPK/Erk to increase the pool of phosphorylated activated Etv4/5, enabling cells to respond more quickly and robustly to dynamic changes in Fgf.
