GPT and Hepatic fibrosis: A primary bone marrow-derived mesenchymal stem cell (BM-MSC) line with typical mesenchymal lineage markers and differentiation potency was transplanted in a CCl4-induced fibrotic C57BL/6 J mouse model (Fig. S1); and the transplantation remarkably attenuated liver fibrosis by decreasing serum alanine aminotransferase (ALT) level, intrahepatic collagen deposition and HSC activation (Fig. 1A–G).
