Fig. 6. Molecular characterization of the phenotype associated with the disruption of Fz5/8 signaling. (A-T) Embryos injected with FzTM1 were fixed at the appropriated stages and processed for whole-mount in situ hybridization with probes for specific markers of embryonic territories, as indicated. (A,B) Early blastula (B3), (C,D,K-N,Q,R) mesenchyme blastula, (E,F) hatched blastula, (G-J,O,P,S,T) gastrula. Lateral views with the animal pole at the top except M,N,Q,R (viewed from the vegetal pole).
