Distribution (%) of SiHa cervical cancer cells at G0/G1, S and G2/M stages of the cell cycle under various culture conditions

Cell cycle stage	48 h with 10% FCS	72 h with 10% FCS	72 h with 0.1% FCS	*16 h with aphidicolin	6 h release frome aphidicolin	12 h release frome aphidicolin	24 h release from aphidicolin
G0/G1	59 ± 0.5	65 ± 1.2	73 ± 1.1	88 ± 1.4	42 ± 1.0	46 ± 0.7	63 ± 2.8
S	5 ± 0.5	7 ± 0.6	7 ± 0.7	6 ± 1.7	22 ± 0.7	9 ± 1.4	5 ± 0.7
G2/M	36 ± 1.1	28 ± 0.1	20 ± 1.1	6 ± 2.0	36 ± 1.1	45 ± 0.7	33 ± 2.1

^*For synchronization, cultures were growth arrested by serum starvation for 2 days followed by μM aphidicolin for 16 h. Data represent means ±s.e.m. (n = 5).
