FIG. 1. Expression of the Rax gene in the transgenic Xenopus F0 founder. A, B: In situ hybridization of the Rax gene in Xenopus embryos at St. 35. In both whole mount and section preparations, Rax was expressed specifically in the neural retina. C, D: Pax6 is also expressed similarly to Rax at this stage of development. E: EGFP expression in transgenic animals at St. 27 (E, F) and St. 31 (G, H). EGFP is local- ized only in the eye region. In H, the neural retina is intensely stained for EGFP and the lens is devoid of staining. |
