Expression profiles of transcription factors and hepatic genes during hepatocyte differentiation. Human embryonic stem cells were differentiated into embryonic stem cell-derived hepatocytes using the P2 protocol. The expression of the indicated genes was analyzed by quantitative RT-PCR at the indicated time points. The missing points for HNF1A and CYP3A4 indicated their levels not detectable. Abbreviations: AFP, α-fetoprotein; FOXA2, forkhead box protein A2.
