Fig. (3) Cytokines induce expression of iNOS and NO production
in human fetal lung epithelial cells. (A) Immature and mature
human fetal lung epithelial cells were treated with cytokines as
indicated. iNOS expression in the cells was determined by Western
blot. (B) Total nitrogen oxides produced by immature and mature
human fetal lung epithelial cells with cytokine exposure was
measured in the media (*p<0.05).
