||FIG. 7. In situ hybridization of tadpole tail cross sections. (A) Composite with stromelysin-3 antisense probe at late stage 62, just
preceding fin resorption. Scale bar, 200 mm. (B) Composite of gene B antisense probe at stage 63. Arrowheads delineate myosepta. Scale bar,
400 mm. (C, D) Peak expression of deiodinase at stage 61 in tissues that will subsequently up-regulate the delayed response genes as
deiodinase levels drop. (C) Exterior section, (D) interior section. Scale bars, 100 mm in C and D.
