Fig. 5. ß-catenin-2, but not ß-catenin-1, is required for normal expression of the early dorsal markers bozozok and squint. Wild-type embryos were injected with 3 mM MO1 (B,E) or 3 mM MO2 (C,F) and compared with uninjected embryos (A,D) for bozozok (A-C) and squint (D-F) expression at 30% epiboly stage. bozozok expression is inhibited by MO2 and squint expression is partially inhibited by MO2; MO1 injection has no effect on expression of these two markers.
