Oligomeric Proanthocyanidin (IMAGE) Neural Regeneration Research Caption Oligomeric proanthocyanidin reduced H2O2-induced apoptosis in retinal ganglion cell line RGC-5 (Hoechst 33342 staining). The left: H2O2 (400 μM) group; the right: and H2O2 (400 μM) + oligomeric proanthocyanidin (20 μM) group. The arrowheads pointed to apoptotic cells.
