BIBF1120 ameliorated STZ-induced DR. (a) TUNEL (green) and DAPI (blue) immunofluorescence staining of retinal cryosections from the normal, DR, and DR plus BIBF1120 groups, scale bar = 50 μm. (b) Mouse retina complexes stained with H&E in the normal, DR, and DR + BIBF1120 groups and DR + DMSO groups, scale bar = 100 μm. GCL: ganglion cell layer; IPL: inner plexiform layer; INL: inner nuclear layer; IS: inner segment; OPL: outer plexiform layer; ONL: outer nuclear layer; OS: outer segment.
