Zebrafish dpr1 and dpr2 require Β-catenin signaling for their dorsal expression. Embryos are at sphere stage. A-D: Zebrafish dpr1 expression. E-H: Zebrafish dpr2 expression. A,B,E,F: Uninjected (Uninj.) wild-type controls. C,D,G,H: Embryos injected with dn-tcf3 RNA do not have expression of dpr1 or dpr2. A,C,E,G are lateral views. B,D,F,H are animal views. Dorsal is to the right.
