Expression of hepatocytic differentiation (A) and stemness (B) genes in SALL4-over-expressing or SALL4-knockdown liver cancer cells. Cells transduced by a retroviral or lentiviral vector were cultured for 3 days. ALB, TTR, CK19 and ABCG2 mRNA expression was detected using qRT-PCR. Data are expressed as mean ± SD (triplicate samples,***p<0.001,**p<0.01,*p<0.05).
