The effect of TNF-α on the DNA content of SiHa cells. The cells were grown in incomplete and complete MEM and treated with indicated concentrations of TNF-α. The data are expressed as the percentage of the fluorescence in the control wells. Each bar represents the mean of individual quadruplicate cultures ± SE (n = 4). "*" denotes p < 0.05 when compared with the control values.
