Figure 2. (A) Survival differences in patients who had OSCC which expressed ALDH (indicated in blue) compared to ALDH negative tumours (indicated in green). Note: relatively poor survival of patients who had cancers which expressed the marker; (B) survival differences in patients who had OSCC which expressed Sox-2 (indicated in blue) compared to Sox-2 negative tumours (indicated in green). Note: there are no significant survival differences in tumours with and without Sox-2 expression; (C) survival differences in patients who had OSCC which expressed Oct-4 (indicated in blue) compared to Oct-4 negative tumours (indicated in green). Note: there are no significant survival differences in patients with and without Oct-4 expression; (D) survival differences in patients who had OSCC which expressed Bmi-1 (indicated in blue) compared to Bmi-1 negative tumours (indicated in green). Note: no significant difference in survival is observed in patients with and without Bmi-1 expression; (E) survival differences in patients who had OSCC which expressed ALDH and Sox-2 (indicated in green) compared to ALDH and Sox-2 negative tumours (indicated in blue). Note: there are no significant survival differences between patients who had tumours with and without cancer stem cell marker expression. OSCC: oral squamous cell carcinoma
