From: Oxygen and the liberation of placental factors responsible for vascular compromise

The effect of oxygen-conditioned placental medium on the release of vasoactive metabolites. The release of vasodilators 6-keto-PGF1α (a) and nitrite (b), and vasoconstrictor ET-1 (c), from cultured UtMVEC following the application of oxygen-conditioned placental explant medium. No significant changes in release were determined as the oxygen concentration decreased; N=8.
