Fig. 6. Tsg knockdown partially suppresses the sizzled (ogon) ventralized phenotype. (A) Dorsal view of the tail of an ogon mutant at 24 hpf showing duplication of the ventral fin fold (arrowheads). (B) The fin fold duplication is suppressed by 8 ng MO1. (C-H) Whole-mount in situ hybridization at 80% epiboly (animal pole views, dorsal towards the right) shows ventral marker eve1 expanded in uninjected mutants (C), whereas the dorsal marker foxb1.2 is reduced (D). Expression of these markers in mutants injected with 25 ng MO5 in E (n=16/22) and F (n=15/20) is similar to that seen in wild type (G,H).
