Figure 4. The relative expression of 7 angiogenesis-related genes between normal liver cell lines and hepatocarcinoma cell lines. ANGTP1 (A), COL18A (B), ITGAV (C), PGF (D) were relatively highly expressed in hepatocarcinoma cell lines, while ENG (E), PON1 (F) had higher expression in normal liver cell lines. (G) There is no significant difference in the expression of PDCD10 in the two cell lines.
