A, B Immunohistological staining of liver sections from P120 PR-SET7ΔHepA mice and control littermates (WT) with Ki67, albumin (Alb) and A6 or HNF4 antibodies as indicated. Arrows depict the different areas in the sections as indicated above (Fig.1B). Asterisks (*) indicate Ki67+ hepatocytes. Small arrows (>) indicate Ki67+ non-hepatic cells. Note the lack of co-staining of cells with HNF4 and A6 antibodies.
