Figure 2From: Cervical squamous carcinoma cells are resistant to the combined action of tumor necrosis factor-α and histamine whereas normal keratinocytes undergo cytolysisThe 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.Back to article page
