Figure 6. Displaced cells and electroporation of a stage 12 optic vesicle. A–B: Fluorescence micrograph of a sectioned retina from an embryonic day 14 (E14) embryo electroporated with the RXRγ208 Cre-LoxP piggyBac constructs in ovo at stage 28, showing a displaced photoreceptor (PR; arrow) and a displaced horizontal cell (HC; arrow). C: Fluorescence micrograph of a sectioned retina from an E14 embryo electroporated with the RXRγ208 Cre-LoxP piggyBac constructs in ovo at stage 12.
