Figure 7. A transgenic fish expressing GFP under the 1.8 Kb zebrafish prep1.1 promoter recapitulates the expression of the endogenous gene during embryogenesis.

Figure 7

A–F: live Tg(-1.8pknox1.1:eGFP)io009 embryos of three different developmental stages (indicated) visualized by confocal (A) or fluorescence microscopy (D, F). Embryos in B, C and E are the same of A, D and F respectively, visualized in transmission (A) and bright field (C, E). G, H, I: In situ hybridization of embryos at the same stage of development with the pknox1.1 antisense RNA-probe, shown in lateral view.
