The antibodies are specific for vascular endothelial growth factor receptor-1 (VEGFR-I) and methods of treating angiogenesis-associated diseases and tumors with antibodies to VEGFR-I.
Figure 1 VEGF-A or -B enhances CRC cell migration
Effect of VEGF-A or -B on CRC cell migration.(a) HT-29 cells were treated with the anti-VEGFR-1 antibody 18F1 and used for transwell migration assays. At 48 h, incubation with VEGF-A or -B significantly increased cell migration, but treatment with the VEGFR-1 antibody blocked this effect. *P<0.0001 vs control cells; bars indicate s.e.m. Similar results were observed in SW480 cells (data not shown).(b) Photographs of migrated cells

Figure 2 VEGF-A or -B enhances CRC cell invasion
Effect of VEGF-A or -B on CRC cell invasion. (a) SW480 cells were treated with the anti-VEGFR-1 antibody 18F1 and transwell invasion assays were performed. At 48 h, incubation with VEGF-A or -B increased cell invasion, but treatment with the VEGFR-1 antibody completely blocked this effect. *P<0.05 vs control cells; bars indicate s.e.m. (b) Photographs of invaded cells

Figure 3 VEGF-A or VEGF-B enhances CRC cell growth in soft agar
Effect of VEGF-A or -B on colony formation in soft agar.(a) HT29 cells were plated in soft agar with or without VEGF-A, -B, or VEGFR-1 antibody (18F1), and colonies were counted 14 days later. Cells treated with VEGF-A or -B formed more and larger colonies than controls; addition of VEGFR-1 antibody decreased colony formation induced by the VEGF ligands. *P<0.03 vs control cells; bars indicate s.e.m.(b) Photographs of colony formation.
