Survival and growth rate of HeLa cells treated with cisplatin

Cisplatin, μM	10-day survival, %	Growth rate
		24 h	48 h
Untreated	100	2.06  ±  0.02	3.95  ±  0.17
0.5	39	1.74  ±  0.03	1.41  ±  0.05
1	4	1.14  ±  0.19	0.85  ±  0.08
2	0	0.96  ±  0.04	0.43  ±  0.09
5	0	0.83  ±  0.06	0.30  ±  0.07

The 10-day survival data come from colony counting. The growth rate is presented as a ratio of the number of cells at a given time point to that at the start of cisplatin treatment. The numbers reported are mean values ±1 SD from three independent experiments.
