Sensitivity of primary HNSCC cell cultures to 5-FU treatment and ionizing radiation. Cell viability (XTT-assay) of HN1957 (a) and HN2092 (b) 48Â h after 5-FU treatment relative to DMSO-controls. Each data point represents the mean of three biological replicates. Dashed lines mark the 5-FU concentrations selected for in vitro radiochemotherapy modeling. Survival curves were generated by colony forming assay for HN1957 (c) 6 days after irradiation and HN2092 (d) 12 days after irradiation. Error bars represent the standard deviation of three biological replicates.
