Problems solved by technology

Limited by this, in the process of cell culture and drug testing, it is difficult to restore the natural state of cells in the organism, so the effect of cytological experiments will be greatly reduced, and the metabolism of drugs and cells in the body cannot be simulated to the greatest extent

Abstract

The invention provides a complete culture medium for culturing hepatocytes. Complete culture medium components comprise a basic culture medium and mixed serum, wherein the mixed serum is composed of portal vein serum and fetal bovine serum. The complete culture medium provided by the invention can be applied to culture of a hepatoma cell line HepG2, and can also enhance the expression of pigment metabolic enzymes in the hepatocytes. The gene expression level of metabolic enzymes in the hepatocytes is enhanced in the premise of ensuring the normal growth of the hepatocytes and the survival of the hepatocytes.

Description

technical field [0001] The invention relates to the field of cell culture, in particular to a complete culture medium for culturing hepatocytes and improving the expression of enzyme genes. Background technique [0002] In the process of drug development and drug testing, drug safety evaluation is an important link, including biochemical analysis, cytology experiments, toxicology experiments, animal experiments and human clinical experiments. If the metabolites in the body can be better simulated at the cellular level in the early stage, it will reduce the risk of failure in animal experiments and human clinical trials in the later stage. [0003] The main organ of drug metabolism in the body is the liver, and the smallest unit that performs metabolic functions is the liver cell. The study of drug metabolism in the body at the biochemical level mainly involves two processes: phase I metabolism and phase II metabolism. Specifically, phase I metabolism refers to that under t...
