Liver transcription program is expressed in HepaRG cells at one week of differentiation. (A) HepaRG differentiation model. For proliferative (progenitor) condition, cells were seeded and trypsinized before reaching 50% confluence; for differentiating conditions, cells were seeded at 70–80% confluence in order to reach 100% confluence 24 h after seeding. (B) Transcriptome was analyzed in both conditions. Heatmap represents differentially expressed genes (DEGs) with fold change greater than four. Cell/tissues types associated with genes down-regulated (C) and up-regulated (D) in differentiating cells (EnrichR), adjusted p-values are shown. (E–H) Expression of hepatocyte markers was validated by RT-qPCR, data represent mean ± SEM 3 independent cultures/condition; *Statistical difference (p < 0.05).
