Detection of CXCL1 protein expression in representative CRA, CRC and CRLM specimens as assessed by immunohistochemical staining with CXCL1 -specific antibodies. (A) Weak immunostaining in apical epithelial cells within tumor neighbor tissues of CRA, (B) weak to medium staining intensities in apical epithelial cells within CRA specimens, (C) weak insular signals in apical epithelial cells and goblet cells within tumor neighbor tissues of CRC, (D) intense ubiquitous epithelial signals and insular mesenchymal signals in CRC tissues, (E) medium staining intensities of fine granular texture in hepatocytes and (F) intense cytoplasmic signals in ubiquitous distribution in CRLM (original magnification 200 and 400 fold, respectively).
