Six1-Expression in the patient cohort. Staining against Six1 was performed and Six1 expression was determined in cytoplasm and cell nucleus on a tissue microarray including human samples of patients with pancreatic cancer. a Negative Six1 expression in cytoplasm and nucleus b Negative Six1 expression in cytoplasm and positive nucleus staining c Weak Six1 expression in cytoplasm without nucleus staining. d Weak Six1 expression in cytoplasm and positive nucleus staining. e Strong Six1 expression in cytoplasm and negative nucleus staining. Annotations above the panel rows indicate the magnification scale of the figures: first and third row: 40× magnification. Second and fourth row: 100× magnification
