:
LIF increased the accumulation of urokinase plasminogen activator (u-PA) in the Hep G2 cell culture supernatants determined by enzyme linked immunosorbent assay ( ELISA ) ( 0.21 +/- 0.03 ( SE ) ng/ml at baseline ; 0.40 +/- 0.05 ng/ml at 100 U/ml, P < 0.05 ; 0.57 +/- 0.06 ng/ml at 500 U/ml, P < 0.01 ; n = 9 ) without altering total protein content
