Figure 3From: The prosurvival role of autophagy in Resveratrol-induced cytotoxicity in human U251 glioma cells Hoechst 33258 staining. Nuclei of U251 cells were treated with Res (150 μM) for 72 h and stained with Hoechst 33258 to detect apoptosis morphologically. Microphotographs were shown as representative results from three independent experiments. ×400. Bar, 50 μm.Back to article page
