Fig 3. Effect of peripheral blood mononuclear cells (PBMC) activated by human chorionic gonadotropin (hCG) on the protein expression of matrix metalloproteinase (MMP)-2, MMP-9, vascular endothelial growth factor (VEGF), and tissue inhibitor of metalloproteinase (TIMP)1 and TIMP-2 in JAR cells by western blotting assays.

(A) Protein expression of MMP-2, MMP-9, VEGF, TIMP-1, and TIMP-2 in control JAR cells or those cultured in hCG, 400, 800, or 1600 μL culture medium supernatant of PBMC with hCG. (B) The intensity of protein expressions of JAR cells compared to control cells using western blot analysis. Data are expressed as mean ± standard error of the mean of triplicate experiments. *, P < 0.05 compared with the control and hCG groups.
