Figure 2. Migratory ability of MCF-7 and MDA-MB-231 clones transfected with RANTES and/or IL-6.
MCF-7 (A) and MDA-MB-231 (B) stable clones were seeded in the inserts and allowed to migrate for 20 h through a fibronectin-coated membrane toward serum containing medium (*P < 0.05; Student’s t-test). EVn: cells transfected with the empty vector (neomycin); EVz: cells transfected with the empty vector (zeocin); EVn+z: cells transfected with both empty vectors.
