Neutralizing anti-VEGF mAb blocks CD40-induced MM cell migration.
MM cells were subjected to transmigration assay and exposed for 8 hours (RPMI 8226 cells) or 16 hours (SV cells) to CD40 activation by sCD40L (0 or 10 μg/mL [μM]), in the presence or absence of neutralizing anti-VEGF mAb (0-5 μg/mL [μM]) added to the lower chamber of the transwell. Migrated cells collected from the lower chamber were counted. Enhanced transmigration of cells induced by sCD40L was abrogated by neutralizing anti-VEGF mAb. (■) RPMI 8226; (▪) SV.
