Fig. 2From: Cell-in-cell structures are more potent predictors of outcome than senescence or apoptosis in head and neck squamous cell carcinomasFrequency and distribution of CIC structures, senescent and apoptotic cells. a Overall frequency of CIC, senescent cells and apoptotic cells in pre-therapeutic biopsies. Distribution of cell events arranged in order of frequency of (b) CIC, (c) senescence and (d) apoptosis. The percentage of tissue samples having positive events, the overall mean (mean) and mean of tumor tissue with positive events only (mean+) is indicatedBack to article page
