Figure 1. Rod photoreceptor cells are cone-shaped at the early stages of development. A: Retinas of tadpoles expressing Opsin-Dend2 or P/rds-Dend2 in rod photoreceptors were imaged for Dend2 fluorescence at 6/7, 9, and 21–22 dpf. Rod photoreceptors are cone-shaped at the early stages of development and become rod-shaped as tadpoles age. B: Eyes of tadpoles expressing Opsin-Dend2 (green) were fixed at 6 dpf and stained with wheat germ agglutinin (WGA, blue) and an antibody against Xenopus peripherin/rds (P/rds, red). Peripherin/rds localizes to rod disk rim (arrowhead) and cone disk rim (arrow) regions that are structurally distinct. Rod and cone photoreceptor cells are indicated in the figure. Opsin-Dend2 is specifically expressed in rod cells. Scale bars = 10 μm. Image published in: Tian G et al. (2014) Copyright © 2014.
