Fig. 7. Analysis of hindbrain markers in Gbx2-/- inner ears.
Dorsal views of +/ (A,C,E) and / (B,D,F) Gbx2
embryos probed for Krox20 (A,B), Epha4 (C,D) and
Hoxb1 (E,F) RNA transcripts at 9 dpc. In Gbx2-/-
embryos, Krox20 (B) and Epha4 (D) expression domains are
reduced in r5, and the anterior border of Hoxb1 expression domain (F)
is aberrant. Arrows indicate the borders of otocysts. Scale bar in A: 100
µm for A-F.
