Oxidative stress and photoreceptor apoptosis in the retina of RD model. (A) The intensity of ROS staining increased significantly after modeling. (B) The TUNEL positive cells were detected in the ONL of RD model at P7, and the cell counts increased progressively. (Scale = 20 µm), the red arrows indicate TUNEL positive cells. (*P < 0.05, **P < 0.01, and ****P < 0.0001, for differences between time points, and ^#P < 0.05, ^##P < 0.01, ^###P < 0.001, and ^####P < 0.0001, for differences between animal groups, n = 6).
