Benzo[a]pyrene (BaP) induces cyclooxygenase-2 and increases 6-keto PGF1α.
Fetoplacental endothelial cell migration and tube formation are inhibited by BaP.
BaP effects on fetoplacental endothelial cells occur via aryl hydrocarbon receptor.
Angiogenic impairment mediates adverse effects of BaP on fetoplacental vasculature.
