Fig. 7B. —57-year-old man with poorly differentiated 5.8-cm
hepatocellular carcinoma (HCC) showing strong vascular endothelial growth
factor (VEGF) expression, dominantly in anteroinferior segment of liver with
chronic type C viral hepatitis. Child-Pugh grade was A. Schematic shows
electrophoretic bands and their corresponding histograms. For calibration,
1.25 mg/mL of VEGF solution was used. Areas of histogram were 376 pixels for
calibration band, 3,485 pixels for HCC band, and 1,395 pixels for surrounding
liver band. VEGF expression index was 9.27 in HCC and 3.71 in surrounding
liver, giving difference in VEGF expression index of 5.56. Note that
electrophoretic peaks adjacent to those of HCC and liver are due to expression
of irregular protein.
