Figure 5

Histology of metastases in nude mice. The bowel containing the tumour nodules was paraffin-embedded, sectioned at 4 μm intervals and stained with hematoxylin-eosin. The left panels represent the lower magnification of the bowel with or without tumour nodules (×40, P7 vs. P59). The squared regions in the left panels are enlarged in the right panels (×400).
