Dkk1b is able to inhibit Wnt/β-catenin and Fgf signaling in the absence of glypican4. (A-D) Expression of the Wnt/β-catenin target lef1 in non-transgenic siblings (A) and glypican4^fr6 mutants (B) in the leading region of the primordium. (C-D) After heat shock, 28–30 hpf transgenic siblings (C) and glypican4^fr6 mutants (D) lose expression of lef1 indicating that Dkk1b is functional and inhibits Wnt target genes. (E-H) The Fgf target pea3 is expressed in the trailing region of the primordium in non-transgenic control siblings (E) and glypican4^fr6 mutants (F) and is downregulated after induction of Dkk1-GFP in both backgrounds indicating that the inhibition of Wnt targets results in the loss of Fgf signaling (G-H).
