Figure Lengend Snippet: Serial sections of normal and diseased pancreatic tissue were stained for CXCL12, CXCR4, CXCR7, and CK19. CXCL12 staining apparent in normal exocrine ducts was diminished in PDAC tissue. CXCR4 staining increased in PanIN and PDAC relative to normal ductal epithelium. CXCR7 expression was variable in normal epithelium, PanIN lesions, and PDAC. (A)Normal tissue from a single patient with healthy pancreas represents observations from 25 different normal tissues from 21 individual patients. (B)PDAC tissue from one patient represents observations from 82 different tissues from 29 different patients. 1000× magnification represents inset box at 200×. (C) Staining was quantified by blinded scoring of serial sections in relation to CK19 staining. (***) denotes P ≤0.001.
