Figure 7From: Identification of pancreatic cancer invasion-related proteins by proteomic analysis IHC detection of STIP1 (A-D) and ALDH1A1 (E-H) in pancreatic cancer and normal pancreas tissues. (A) Strong STIP1 cytoplasmic staining in PC tumour ducts. (B-C) Strong STIP1 expression in poorly differentiated PC tumours. (D) Moderate staining of normal pancreas ducts and acinar cells. (E) ALDH1A1 highly expressed in well differentiated PC tumour. (F-G) Weak ALDH1A1 staining observed in < 10% of poorly differentiated PC tumours. (H) Positive staining in epithelial cells of normal pancreas. Original magnification 200×.Back to article page
