Images of immunohistochemical galectin-1 stainings (A: brown) and galectin-9 stainings (B: brown) of three representative tumors.

<p>Staining was observed in tumor cell compartment (T), stromal compartment (S) and in tumor endothelial cells (arrows). The inset on the left shows the isotype control staining. Scale bar = 50 micrometer. The bar graphs showing quantification of IHC scores for galectin-1 and galectin-9 in different tumor compartments.
