Fig. 3 Expression of nkx2.2a in the ventral hindbrain is smoothened-dependent but up-regulated in hdac1 mutant embryos. (A–H) Expression of nkx2.2a in hindbrain of (A,C,E,G) wild-type sibling, (B) smoothened (smoh) mutant and (D,F,H) hdac1 mutant embryos at (A,B) 32 hpf, (C,D) 28 hpf, (E,F,G,H) 50 hpf. Panels A–F show transverse sections through the hindbrain of embryos at the level of rhombomere 5 and panels G,H show dorsal views of (G) wild-type and (H) hdac1 mutant hindbrain, demonstrating that expression of nkx2.2a in the ventral medial hindbrain is stably increased by loss of hdac1 function.
