Induction of apoptosis on HL1-NB cells treated with resveratrol: analysis by fluorescence microscopy. Detection of apoptotic cells was performed by microscopical examination of nuclei after staining with Hoechst 33342 of tumoral cardiac mouse HL-1 NB cells cultured in the absence or in the presence of resveratrol (Rsv: 30 μM) for 48 and 72 h. Normal cells have round and regular nuclei whereas apoptotic cells have condensed and/or fragmented nuclei
