Fig. 1From: Significant co-expression of putative cancer stem cell markers, EpCAM and CD166, correlates with tumor stage and invasive behavior in colorectal cancerImmunohistochemical staining of EpCAM and CD166 in colorectal cancer specimens and adjacent normal tissues. A Higher, B lower, and C negative expression of EpCAM in colorectal cancer tissue. D Higher and E lower expression of EpCAM in adjacent normal tissue. F Higher, G lower, and H negative expression of CD166 in colorectal cancer tissues. I Higher and J lower expression of CD166 in adjacent normal tissue. K and L preimmune rabbit IgG as negative controls for EpCAM and CD166, respectively (all images were taken at 100× and 200× magnification)Back to article page
