the effect of urokinase on induction of urokinase receptors by combinations of ifn-gamma and tnf-alpha varied with the dosage of tnf-alpha : a combination of ifn-gamma ( 200 u/ml ) and tnf-alpha ( 15 u/ml ) induced 38,000 receptors/cell in the presence and 90,000 receptors/cells in the absence of urokinase , whereas ifn-gamma ( 200 u/ml ) and tnf-alpha ( 20 u/ml ) induced 90,000 receptors/cell in the absence and presence of urokinase .
