Fig. 2. Marker gene expression in the interrenal primordium. In situ hyridization
showing expression of scc (A), 3ß-HSD (B) and
ff1b (C) in the region ventral to the third somite and wt1
(D) expression in a wider region ventral to the second and third somites at 36
hpf. (E-J) Co-expression of ff1b and scc at 30 (E-G) and 33
hpf (H-J). Green indicates scc expression, red indicates
ff1b expression and yellow indicates the merged signal of
scc and ff1b.
