Fig. 5 The expression of fgf8 and the phenotype of fgf8-morphant. Medaka fgf8 is expressed in the anterior tip of the forebrain, MHB, hindbrain and tailbud (A, B). The expression of fgf8 is largely unaffected in the fgfr1^hdf mutant, except for the expression in tailbud (C, D; arrows). Injection of fgf8 morpholino causes somite-less phenotype, phenocopying the fgfr1^hdf mutant phenotype (E, G). Same as fgfr1^hdf, morphology of the brain including MHB is normal in the fgf8 morphant (H). The expression of krox20 and ntl in wild-type (I, J) and fgf8 morphant (K, L). In the morphant, the expression of krox20 in r5 is lost at st. 18, and is recovered at st. 20 (K, L; arrows). The expression of pax2 and ntl in wild-type (M, N) and fgf8 morphant (O, P). The expression of pax2 in MHB is not affected in the morphant.
