Determination of HN cell proliferative activity as a function of αvβ6 expression. The cell proliferative activity was measured by MTT assays over 5 days. The relative absorbance (OD₅₇₀ value) is presented as measure of cell numbers. HN WT cells proliferated significantly faster than HN INTGB6KO cells. P values are shown above the bars
