Quantitative analysis of TUNEL-positive cells (mean values of a, b, c, d, e, and f sites) in retinal sections. (A): NK-4 (0.0001 mg/mL)-injected retinas vs. control groups; (B): NK-4 (0.001 mg/mL)-injected retinas vs. control groups; (C): NK-4 (0.01 mg/mL)-injected retinas vs. control groups; (D): NK-4 (0.1 mg/mL)-injected retinas vs. control groups. The number of TUNEL-positive cells was significantly decreased in the ONL of the eyes injected with higher concentrations of NK-4, ranging from 0.001 to 0.1 mg/mL, compared with control vehicle-injected eyes (p < 0.0001, p = 0.001, p < 0.0001, respectively, one-factor ANOVA, post hoc test). **: p < 0.01, ***: p < 0.001.
