Figure 3

HNSCC tumor samples display heterogeneity in response to IR. (A) Schematic representation of the experimental setup. (B) changes in % of EdU cells, relative to untreated control, in the resistant, intermediate and sensitive group of samples. Each point represents the mean of ≥4 FoV per sample, and for clarity no SEM is displayed. Dashed lines mark 30% and 60% of the proliferation of untreated control. (C) Change in % of TUNEL positive cells upon five days of culture. Each graph bar represents the mean of ≥4 FoV and error bars represent SEM. (D) Difference in % of TUNEL positive cells between the resistant and sensitive group relative to untreated control. Graph bars represent the mean of three samples and error bars represent SEM. A t-test was used to determine significance. * p < 0.05, ** p < 0.01.
