Fig. 5. Markers of early placode induction are absent in hsy. (A-F) In
situ hybridizations with three- to five-somite stage embryos: dorsal views,
anterior towards the left. (A,C,E) wild-type and (B,D,F) hsy embryos.
(A,B) pax8 expression, (C,D) pax2a expression and (E,F)
dlx3b expression. (G) TaqI genotyping for dlx3b in
situ. Migration position for hsy mutant and wild-type fragments are
indicated at the left of the gel. mhb, midbrain-hindbrain boundary; ot, otic
primordia; pn, pronephros.
