Immunohistochemistry for PC2 in normal and unaffected liver compared to colorectal (CRC) liver metastases. A. Light microscopy PC2 immunohistochemistry of normal liver (N), using 400 × magnification. Arrowheads indicate positively stained hepatic cells. B. Light microscopy PC2 immunohistochemistry of liver metastasis (T) and adjacent unaffected parenchyma (U), using 25 × magnification. Arrowheads indicate positively stained cells mainly in the unaffected liver. C. Light microscopy PC2 immunohistochemistry of liver metastasis (T) using 200 × magnification. Arrowheads indicate positively stained tumor cells.
