Figure 1: In situ hybridization for MMP-2 in colorectal tumor sections. Staining by BCIP/NBT (bluish-black) and counterstaining with nuclear fast red, red arrows show positive cells, whereas black arrows show negative cells. (a) Well-differentiated adenocarcinoma, Duke's stage A, number of stained cells (99%); (b) moderately differentiated adenocarcinoma, stage B (95%); (c) moderately differentiated adenocarcinoma, stage C (85%); (d) poorly differentiated adenocarcinoma, stage D (35%); (e) resection margin. Magnification power for a-e (×400)
