    Fetal bovine serum (FBS) has been the standard in cell culture but introduces variability and ethical concerns.

  • 2

    Chemically defined media (CDM) are emerging as alternatives to FBS, aiming to provide consistent and interpretable culture conditions.

  • 3

    HepaRG and HuH7 cells are widely used hepatic models, but their transcriptomic profiles can be influenced by culture conditions.

  • 4

    This study evaluates how CDM affects the transcriptomic state of HepaRG and HuH7 cells compared to primary human hepatocytes.

  • 5

    The findings highlight the importance of systematic benchmarking of CDM against traditional serum-based conditions in liver research.
