Angiostatin generation by human tumor cell lines: Involvement of plasminogen activators
15 Jun 2000
Abstract excerpt
Angiostatin is a tumor-derived angiogenesis inhibitor consisting of an internal fragment of plasminogen. Little is known about the production of angiostatin by human tumors. In this study, we examined the in vitro angiostatin-generating capacities of a panel of human tumor cell lines (total n = 75) and the proteolytic molecule(s) involved. Angiostatin formation was determined by assessing the level of plasminogen...
