PC12 cells were stained with the DNA-binding fluorochrome Hoechst 33342. a Fluorescence micrographs of PC12 cells from control group, pretreated with Gen (0, 12.5, 25, 50, 100 μM) for 2 h followed by incubation with 20 μM Aβ25–35 for another 24 h (scale bar 100 μm). b The percentage of PC12 cells with apoptosis was estimated. *p < 0.05 compared to control; #p < 0.05 compared to Aβ25–35 alone
