Effect of environmental light conditions on outer nuclear layer. (A–F) Cross-sectional cryosections of retinas from P30 C57BL/6J mice (A–C) and rd10 mice (D–F) maintained under 5, 50, and 300 lux cyclic light. Images correspond to the central area of the retina, near the optic nerve. (G, H) Mean number of photoreceptor rows along central sections of the retina from C57BL/6J mice (G) and rd10 mice (H) reared under the different light conditions (n = 3 to 7). Two-way ANOVA and Tukey's post hoc test. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 for comparisons between animals housed at 50 and 300 lux. †P < 0.05, ††P < 0.01, †††P < 0.001, ††††P < 0.0001 for comparisons between animals housed at 5 and 50 lux. INL, inner nuclear layer; ONL, outer nuclear layer; ON, optic nerve. Scale bars: 50 µm.
