aExperiments were repeated three times with similar results; this table presents the result of one experiment.
bG0 cells were isolated using Hoechst-Pyronin Y-based fluorescence-activated cell sorting.
cThe t-test was carried out to determine the difference between the two groups in three experiments: cP < 0.01.
