Correlation between expression and differentiation of endocan in colorectal cancer

Figure 1 Expression of endocan in normal mucous membrane and cancer tissues of colon and rectum tissues. A: Endocan was expressed in the cytoplasm of the epithelial cell and it had a high polarity under the nucleus; B: The expression of endocan in colon and rectum tissues. This section show that it had a high expression in mucous membrane by the side of carcinoma tissue (gray arrow), also in well and moderately-differentiated colon carcinoma tissues (black arrow), but a weak expression in poorly differentiated carcinoma tissues (white arrow).
