    • PURPOSE: A method for preparing hepatocytes with liver-specific function using MSC(mesenchymal stem cells) is provided to be used as hepatocyte source for evaluating toxicity. CONSTITUTION: A method for preparing hepatocytes comprises: a step of treating MSC(mesenchymal stem cells) with cell growth factor in a serum-free medium containing a serum substitute to induce hepatocytes; a step of treating cell growth factors, cytokines, and biochemicals in the serum-free medium to mature the hepatocytes. The mesenchymal stem cells are derived from bone marrow, fat, and umbilical cord blood. The serum substitute is knockout TMserum replacement. The cell growth factor includes FGF-1(fibroblast growth factor), FGF-2, FGF-4, and mixture thereof. The biochemical includes dexamethasone and DMSO.
    • 目的:使用MSC(间充质干细胞)制备具有肝脏特异功能的肝细胞的方法用作肝细胞来评估毒性。 构成:制备肝细胞的方法包括:在含有血清替代物的无血清培养基中用细胞生长因子处理MSC(间充质干细胞)以诱导肝细胞的步骤; 在无血清培养基中处理细胞生长因子,细胞因子和生物化学物质以使肝细胞成熟的步骤。 间充质干细胞衍生自骨髓,脂肪和脐带血。 血清替代品是淘汰TMserum替代品。 细胞生长因子包括FGF-1(成纤维细胞生长因子),FGF-2,FGF-4及其混合物。 生物化学包括地塞米松和DMSO。
