Construction of a spheroid array culture system on a suspended permeable hydrogel membrane scaffold for improving the expression of a liver-specific drug-metabolizing enzyme of HepG2 cells†
Abstract
Herein, we constructed a spheroid array culture system on a flexible hydrogel membrane suspended in the culture medium. When we applied this culture system to HepG2 cells, the results suggested that an aerobic culture environment was implemented, and the gene expression of a liver-specific drug-metabolizing enzyme was improved in comparison with that of the conventional immobilized monolayer culture.
