STIMULATION, MODULATION AND/OR INHIBITION OF ENDOTHELIAL PROTEOLYTIC ACTIVITY AND/OR ANGIOGENIC ACTIVITY

摘要

Vascular endothelial growth factor-B (VEGF-B) and vascular endothelial growth factor-C (VEGF-C) are angiogenic polypeptides. It has been shown that VEGF-B and -C are angiogenic in vitro especially in combination with bFGF. VEGF-C also increases plasminogen activator (PA) activity in bovine endothelial cell lines and this is accompanied by a concomitant increase in PA inhibitor-1. Addition of alpha-2-antiplasmin to bovine endothelial cells co-treated with bFGF and VEGF-C partially inhibits collagen gel invasion.
