eGFP expression patterns in Tg(ola.sp7:nlsGFP) zebrafish. (A), At 1 d postfertilization (dpf), GFP is weakly expressed in the posterior trunk and tail regions. (B), Until 8 dpf, GFP‐labeled osteoblasts are detectable in ceratobranchial, opercle, branchiostegal rays, and mandible of the head region. (C), The rostral skeleton, axial skeleton, fin, and tail vertebral columns are clearly labeled by eGFP in 30 dpf juvenile fish. (D), Fluorescent fish scales are visible in 42 dpf transgenic fish. CT, cleithrum; BR, branchiostegal rays; MD, mandible
