(A) The tumor volume resulting from subcutaneous inoculation of SKOV-3 cells in athymic female nu/nu mice treated with mouse monoclonal anti-hVEGF antibody, rabbit polyclonal anti-MVF-VEGF(102-122) antibodies or anti-MVF-VEGF(127-144) antibodies was significantly smaller compared to PBS control mice from 11 days after inoculation, p<0.01). There is no difference in tumor volume between mice treated with normal rabbit IgG and mice of PBS control (p>0.05). (B) Immunostaining for endothelial cells (CD31) demonstrated reduced microvessel density in tumors from mice treated with mouse monoclonal anti-hVEGF antibody, rabbit polyclonal anti-MVFVEGF(102-122) antibodies or anti-MVF-VEGF(127-144) antibodies is significantly lower than that of mice treated with PBS (p<0.01). There is no difference in tumor microvessel density between mice treated with normal rabbit IgG and mice treated with PBS (p>0.05).
