Immunohistochemistry for CTHRC1 on HCC tissues. (A and B) Strong positive staining for CTHRC1 was observed in the HCC cells close to fibrous boundaries, while non-tumor parts were negative for CTHRC1. (B, arrowheads) HCC cells invading surrounding normal liver tissues were strongly positive for CTHRC1. T, tumor; NT, non-tumor. Original magnification, ×200.
