Fig. 3. Marker analysis in the mouse hindbrain at 9.5 dpc.
(A,B) Hoxa2 in situ hybridisation on flat mounted
hindbrain in wild-type (A) and mutant (B) embryos. (B) Arrow points to the
abnormal proximal pa2 on the left side. (C,D) EphA4 in
situ hybridisation in wild-type (C) and mutant (D) embryos.
(E,F) Hoxb1 in situ hybridisation in wild-type (E) and
mutant (F) embryos. No significant difference was observed in the mutants for
these three markers.
