Human serum-supplemented cell culture conditions improve xenobiotic metabolism in hepatoma cell lines HepG2 and Huh7

1

HepG2 and Huh7 cell lines are valuable for studying xenobiotic metabolism but exhibit lower CYP expression compared to primary human hepatocytes.
2

Human serum supplementation enhances metabolic activity and enzyme expression in HepG2 and Huh7 cell lines, potentially improving in vitro toxicology studies.
3

Fetal bovine serum raises ethical concerns, prompting the exploration of human serum as a cost-effective alternative for cell culture.
4

The study assessed metabolite formation from CYP enzymes in HepG2 and Huh7 cells using a dual-cocktail approach with synthetic cathinones.
5

Optimizing nutritional conditions in hepatoma cells can better simulate human metabolic capacity, aiding in drug metabolism and toxicokinetics research.
