1205Lu cells were exposed to 3T3-F442A EV (3T3-EV) and treated, or not, with Mdivi-1. Cell migration was then evaluated in Boyden chamber assays (left panel; n=6). Right panel, 3T3-F442A EV were added to 1205Lu cells, which were immediately treated, or not, with Mdivi-1. Cell motility was then tracked by video microscopy (n = 40 cells per group) (right panel).
