  sub:_5 prov:value "The main role of uPA in extracellular proteolysis is a generation of cell surface associated plasmin cleaving the main components of the basement membrane and of the extracellular matrix and activating matrix metalloproteinases, which degrade the components resistant to plasmin [1, 3, 42]. Essential for the proteolytic function of uPA is its ability to directly or via plasmin production activate latent or release matrix-bound growth factors. Thus, uPA itself proteolytically activates proforms of hepatocyte growth factor (HGF), of macrophage-stimulating protein (MSP), and of an isoform of vascular endothelial growth factor (VEGF189) [43, 44]." ;
