Figure 3.

DAPI staining of HeLa cells cultured with or without cisplatin. DAPI-stained cells were viewed by fluorescence microscopy using iplab spectrum p software. (A) Percentage of cells having a condensed nucleus. A total of 200 cells was scored in each view, and three views were obtained for each sample. The average from three independent experiments is shown. Error bars represent one standard deviation. (B) Representative cells 24 h (Upper) and 48 h (Lower) after treatment. (Left) Untreated; (Center) 0.5 μM cisplatin; (Right) 5 μM cisplatin.
