Similar RGC densities in adult mKO and littermate floxed control mice.

(A) Representative en face (top) and β-III-tubulin-immunolabeled retinal flat-mounts taken from littermate floxed control and mKO mice; scale bar: 50 μm. (B,C) Schematic illustration of RGC quantification (B) and RGC densities in adult littmate floxed and mKO mice (C; n = 6/group). No significant difference (NS) was noted between the floxed and mKO mice (P = 0.98; two-tailed student t test).
