Real-time PCR revealed that Oct4A was highly expressed in T3A-A3 cells compared with some of other T3A clones and hepatoma cell line Bel7402 (Figure 2A), while CD144, CD105, and CD31 were markedly expressed in EGM-induced T3A-A3 cells than in control cells (Figure 2B). This evidence concerns the gene PECAM1 and hepatocellular carcinoma.
