RENBP and cancer: In order to identify different types of molecules supporting cancer-HBME adhesive interactions and to observe whether the molecular involvements are time-dependent, we performed pre-incubations of both cancer and HBME cells with function-blocking antibodies (10 μg/ml) against TF-Ag, integrin β1, integrin α3, and galectin-3 (Gal-3) for 45 min.
