Figure 5. Confocal images showing Cx43 expression in the control and light-damaged retina. A: Cx43 immunoreactivity was limited to the ganglion cell layer in the normal control retina. B–F: Cx43 immunolabeling in the retina at various recovery time points following light damage; there was no apparent change in the expression levels. Abbreviations: ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer; BV, blood vessels; LD, light damage. Scale bar = 50 µm.
