Effect of ambient oxygen changes on platelet activating factor production by fetal ovine endothelial cells.


To determine whether platelet activating factor (PAF) plays a role in the responses seen in the fetal and transitional circulations, we assessed endogenous release of PAF in cultured fetal ovine endothelial cells from the pulmonary artery (PA), ductus arteriosus (DA) and aorta (Ao) under basal conditions and following exposure to hypoxia or hyperoxia.
