Figure 1 Analysis of osteoglycin expression. RT-PCR analysis (A) and Western blot analysis (B) of osteoglycin expression in mouse hepatocarcinoma cells; relative signal intensities of osteoglycin mRNA (C) and protein (D) levels were normal as against those of β-actin by LabWorks (UVP GDS-800 Version 4.0) analysis (compared with F cells, aP < 0.05). F: Hca-F cells; P: Hca-P cells; F(+): Hca-F cells transfected with pIRESpuro3 osteoglycin(+); F0: Hca-F cells transfected with pIRESpuro3. β-actin was used as an internal control.

Figure 2 Metastatic lymph nodes of tumor-burden mice inoculated with Hca-F cells (A), Hca-F cells transfected with pIRESpuro3 (B), or Hca-F cells transfected with pIRESpuro3 osteoglycin(+) (C). Lymph nodes of tumor-burden mice were HE stained and examined under microscope.

F: Hca-F cells; P: Hca-P cells; F(+): Hca-F cells transfected with pIRESpuro3 osteoglycin(+); F0: Hca-F cells transfected with pIRESpuro3.
