Cell-cell adhesion of wild-type THP-1 cells is inhibited by anti-uPAR antibodies.
Wild-type (nontransfected) THP-1 cells were incubated with normal RPMI medium (control) (A) or with 5 μg/mL anti-uPAR antibodies (B) for 3 days. As shown, the presence of the anti-uPAR antibody reduces the ability of the cells to clump.
