these cytosol preparations inhibited the fibrinolytic activity initiated by some plasminogen activators ( e.g . urokinase , rabbit endothelial cell activator ) , but not others ( e.g . activators associated with bovine endothelial cells and rous sarcoma virus-infected chick embryo fibroblasts ) , suggesting that inhibition occurred at the level of plasmin formation , not plasmin activity .
