Fig. 8. TrHBMECs treated with vimentin siRNA or cytochalasin D assemble small FCs. TrHBMECs, expressing YFP-ß3 integrin, were transfected with control siRNA (A) or vimentin siRNA (B) and after 72 hours were viewed in the live state. In C, TrHBMECs were treated with the 0.1 µM cytochalasin D for 30 minutes prior to observation. Note that FCs appear smaller in B and C than in A. Scale bar: 5 µm.
