Abstract:
A method for producing a hepatocyte which is derived from an amnion epidermal cell is provided to treat liver diseases through the transplantation of cell and be used as a hepatocyte source for toxicity evaluation. A method for producing a hepatocyte which is derived from an amnion epidermal cell having the functions of albumin synthesis, urea synthesis, and ammonia removement comprises: a step of preparing amnion epidermal cell; a step of culturing the amnion epidermal cell in medium; and a step of differentiating the amnion epidermal cell to hepatocyte in serum medium in which a HGF (hepatocyte growth factor) is added. The serum medium contains mixture medium having DMEM(Dulbecco's Modified Eagle's Medium) and F-12 in a ratio of 3:1, fetal bovine serum, L-glutamine, hydrocortisone, insulin, transferring, epidermal growth factor, cholera toxin, triiodotyronine, and glucagon.
Abstract:
A method for manufacturing mesenchymal stem cell derived hepatocyte is provided to differentiate a mesenchymal stem cell which is derived from a wharton's jelly. A method for manufacturing mesenchymal stem cell derived hepatocyte comprises: a step of culturing the mesenchymal stem cell in cell proliferation medium; a step of inducing cells to hepatocyte in serum medium in which cell growth factor is added; and a step of maturing hepatocyte in serum medium in which a hepatocyte maturing induction material is added. The hepatocyte maturing induction material is selected from an oncostatin M, glucagon, nicotin amide and dimethyl sulfoxid(DMSO).
