Fig. 8 Expression of bmp2b, 4, and 7 in embryos injected with dlx3b-MO and dlx4b-MO at 90% epiboly. Expression in wild-type embryos of bmp2b (A), bmp4 (C), and bmp7 (E). Expression in 20 ng ATG-dlx3b-MO/20 ng ATG-dlx4b-MO-injected embryos of bmp2b (B), bmp4 (D), and bmp7 (F). (A and B) show that there is a strong triangle of bmp2b expression (arrowhead) at the border of the non-neural ectoderm in the wild-type embryos but this region is lost in MOs-injected embryos. Ventral bmp2b expression persisted in MOs-injected embryos (arrow). No alterations are seen in the expression of bmp4 and bmp7 between wild-type embryos and MOs-injected embryos (C–F). Lateral views, and dorsal is to the right.
