E-cadherin and CXCR3-B IHC staining of patients’ primary prostate tumors and paired metastases. a Representative images of E-cadherin (E-cad) and CXCR3-B staining from paired primary and liver metastatic PCa. E-cadherin and CXCR3-B staining were performed on sister sections, the same areas were imaged. Representative E-cad positive (+) or negative (or low, −) images from same section are shown. b Representative images of E-cadherin (E-cad) and CXCR3-B staining from paired primary and lung metastatic PCa. Representative E-cad positive (+) or negative (or low, −) images from the same section are shown. Black arrows, tumor stroma; Black arrows with solid triangle head, tumor area; Red arrows point out the membrane staining of CXCR3-B. Bar = 25μm
