Fig 8. White blood cells present in the inner plexiform layer in hyperoxia-induced proliferative retinopathy.

(A) Retinal cross sections were immunostained with (A) F4/80 (red) or (B) CD45 (green) and counterstained with DAPI (blue, N = 3). In RA, there was no F4/80 or CD45 staining. In HIPR, F4/80 and CD45 were both seen in the IPL at P21 and P28. Scale bar, 50 μm. INL, inner nuclear layer. IPL, inner plexiform layer. RGCL, retinal ganglion cell layer.
