Association between hypoxia, TILs apoptosis and EMAP-II in CRC in vivo. (A) Immunohistochemical staining of a moderately differentiated adenocarcinoma of the colon with polyclonal anti-CA IX antibody. There is a strong membranous and cytoplasmic staining within the malignant epithelial cells (original magnification × 200). (B) TILs in tumourous tissues were strongly reactive with antiactive caspase-3 antibody (original magnification × 400). (C) Apoptotic TILs immunostained against cleaved PARP antibody (original magnification × 400). (D) Strong brown cytoplasmic staining of malignant epithelial cells in the tumour with EMAP-II (original magnification × 200).
