The PI3K/AKT signaling pathway was required for hepatocyte differentiation. (A): Immunoblot analysis of the indicated proteins in definitive endoderm (DE) cells treated with the indicated growth factors for 15 minutes. (B, C): Differentiated cells were treated with or without LY294002 (10 μM) from day 8 to 24. The expression of the indicated genes was analyzed by qRT-PCR. *, p<.002 versus control in (B); *, p<.02 versus control in (C). (D): Immunoblot analysis of the phosphorylated AKT, HNF4α, and HNF1α in the DE cells treated with or without LY294002 (10 μM) for 24 hours. Abbreviations: HGF, hepatocyte growth factor.
