Masson’s Trichrome and immunohistochemistry was done as described before21 (link),22 (link). For immunofluorescence staining, liver sections were blocked (1% bovine serum albumin in 0.5% PBS-TritonX) and incubated in primary antibodies: F4/80 (AbD Serotec), GFP (Rockland), and BrdU (Cell Signaling). The primary antibodies were detected using AF488 (Vector) and AF647 (Vector). Proliferation in hepatic cells was measured using BrdU uptake. Mice received an IP injection of BrdU 24 h prior to death (50 mg/kg of animal weight).
