Representative immunohistochemical staining for CXCR4 in non-tumor tissue and tumor pancreatic tissue using hematoxylin and eosin staining. A CXCR4 positive cytoplasmic expression in a PDAC tissue; magnification × 8. Inset, the expression of CXCR4 in tumor cells, stromal cells, and inflammatory cells (A1, A2, A3, respectively); magnification × 40; B CXCR4 negative cytoplasmic expression in stromal cells in non-tumor tissue; magnification × 17.2; C CXCR4 positive cytoplasmic expression in stromal cells in tumor pancreatic tissue; magnification × 17.2. The arrows indicate the stromal cells which show positive or negative staining for CXCR4, respectively
