CXCL14 and colorectal carcinoma: When analyzing the levels of CXCL14 expression in colorectal carcinoma tissues by immunohistochemistry, we found an interesting phenomenon that the number of CXCL14-immunopositive carcinoma cells increased as carcinoma cells invaded deeply and the tumor regions that were more close to the invasion front showed stronger CXCL14 immunoreactivity.
