Optimization of Three-Dimensional Culture Conditions of HepG2 Cells with Response Surface Methodology Based on the VitroGel System

This study optimizes three-dimensional (3D) culture conditions of HepG2 using response surface methodology (RSM) based on the VitroGel system to facilitate the cell modelHepG2 cell was 3D cultured on the VitroGel system. Cell viability was detected using Cell Counting Kit-8 (CCK-8) assay of HepG2 lived cell numbers. The proliferation of HepG2 cell and clustering performance was measuredThe selected optimal culture conditions are as follows: concentration of inoculated cells was 4.44 × 10This study serves as a reference for the 3D HepG2 culture and constructs liver tissues
