Figure 12. Retinal ganglion cell survival at 24 h post ischemia-reperfusion injury in the rat retina. The retinal ganglion cells (RGCs) were labeled with Brn3a. The cell counts are relative to the contralateral eye. Three animals per group were analyzed. A: Naïve rat retina. B: Ischemia reperfusion (IR)-injured rat retina. C: IR-injured rat retina treated with 0.8 mM U0126. D: IR-injured rat retina treated with 5% dimethyl sulfoxide (DMSO). E: Percentage of ganglion cell survival in the IR-injured rat retina. Scale bars=10 μm. *p<0.01.
