Reversible cellular adhesion to vitronectin linked to urokinase receptor occupancy.

Abstract excerpt

Urokinase receptors are distributed on surfaces of many cell types where they are thought to focus plasminogen-dependent proteolysis important to migration and tissue remodeling to the immediate pericellular space. In addition to its well characterized role in proteolysis, urokinase receptor binding per se promotes the adhesiveness of leukemic cell lines exposed to differentiating cytokines in vitro. We sought to...
