Fig. 2 Gal4-VP16-mediated expression in comparison to conventional DNA-construct expression. Lateral views of the hindbrain (A, C, E) and trunk (B, D, F) of CMV-lyn-injected (A, B), CMV-GVP/Ulyn-coinjected, and EF-GVP/Ulyn-coinjected embryos at 3 dpf. Pictures represent pseudocolored composites of single optical sections using confocal microscopy. EGFP-expressing cells are displayed in green. Embryos where counterstained with Bodipyceramide TexasRed (Molecular Probes) displayed in red to visualize overall morphology. Note the precise membranelocalization of the lynEGFP-fluorescence in expressing cells (e.g., neuron in A or muscle cells in D). Abbreviations: nc, notochord; nt, neural tube; otv, otic vesicle; rh, rhombencephalon.
