CULTURE METHOD FOR LONG-TERM MAINTENANCE AND PROLIFERATION SUBCULTURE OF HUMAN HEPATOCYTES

摘要

A method for culturing hepatocytes involves maintenance, proliferation, and passaging of the hepatocytes. The method includes culturing the hepatocytes in a culture medium, which includes a hepatocyte basic medium; CHIR99021, which is a GSK-3 beta inhibitor at a concentration of 0.5-10 μM, SB 431542 or A83-01, which are RGF beta inhibitors, at a concentration of 0.5-10 μM, N-acetyl-cysteine at a concentration of 0.25-25 mM; and Oncostatin M at a concentration of 1-100 ng/mL There is no exogenous gene introduced into the hepatocytes, and the genetic background of the hepatocytes is not changed.
