(A) Paraffin liver sections were subjected to Sirius Red staining. T: Tumors, N: Non-tumor regions. (B) Fibrotic regions were quantified based on Sirius Red staining in no-tumor (normal), HCC, and CCA regions. Bars are average ± SD (n = 3–5 livers). (C) Immunohistochemistry of active caspase-3. Nuclei were counterstained with hematoxylin. (D) Active caspase-3-positive cells were quantified. Bars are average ± SD (n = 3–5 livers). (E) Ki67 immunohistochemistry. Nuclei were counterstained with hematoxylin. (F) Ki67-positive cells were quantified. Bars are average ± SD (n = 3–5 livers). One-way ANOVA with post-hoc Tukey was performed in (B, D, and F): ns, not significant.
