Ourimmunostaining approach allowed for the discrimination betweenCXCL12, CXCR4, and CXCR7 expression levelswithin adenocarcinoma, tumor-associated fibroblasts, endothelium, and normal ducts and revealed a pronounced decrease in chemokine within the malignant ductal cell. Here, CXCR4 is linked to adenocarcinoma.
