Distribution of full length and cleaved galectin-3 in the xenografts: Full length galectin-3 is localized on the peripheral cells of the 11-9-1-4 xenograft (arrow), cleavage products are seen in peripheral (arrow) as well as luminal (wider arrow) cells of the section, MMP-9 is localized more intensely in the luminal cells of the section (wider arrow), where cleaved form of galectin-3 is predominant. In M33+64, monoclonal (mAb), polyclonal antibody (pAb) as well as anti-MMP-9 showed a more uniform distribution throughout the section. Bar: 100 micron
