Fig. 3
Characterization of Tg(otpb.A:egfp)zc48; confocal images of whole mount embryos double-labeled for GFP and for TH immunohistochemistry, ventral views, anterior to the top. Scale bar is 50 μm. (A) Schematic diagram of TH-positive cell groups in the zebrafish brain at 72 hpf, based on Rink and Wullimann (2002). (B) Confocal z-stack projection of TH immunohistochemistry at 72 hpf in the zebrafish brain. (C) Confocal z-stack projection of GFP immunohistochemistry in Tg(otpb.A:egfp)zc48. (D–D3) Confocal z-stack projections at different dorsal–ventral levels in the brain of Tg(otpb.A:egfp)zc48 at 72 hpf, showing co-expression of TH and GFP in diDA neuron groups 4 and 6, but not groups 1 and 2 (arrow); arrowhead points to the NPO neurons. (E–E3) Magnified views of the region boxed in B3, showing extensive overlap of GFP-positive neurons in the diencephalon with TH expression. (F–F3) Expression at 24 hpf. (G–G3) Expression at 48 hpf.
