HepG2 cells, an endoglin-negative human hepatoma cell line [38], showed only 0.44% endoglin expression (Figure 6Bv), which was significantly different from that of hepatocytes in patient sera induction group (p = 0.077), but not from hepatogenic cocktail induction group (p = 0.026). The gene discussed is ENG; the disease is hepatocellular carcinoma.
