Cells were cultivated for 24 h. The harvested cells were washed with PBS and fixed with ice-cold 70% ethanol overnight. The fixed cells were resuspended in PBS (containing 0.2 mg/mL RNAse and 10 mM PI) and incubated in the dark for 30 min at 37 degrees. A FACSCalibur flow cytometer (Becton Dickinson, San Jose, CA) was used for flow cytometric analysis, and the results were analyzed using a correlation test.
