Adaptive angiogenesis in placentas of heavy smokers.
Smoking in pregnancy increases perinatal morbidity and mortality, suggesting impaired placental function, though placental weight is increased. We used scanning electron microscopy to show adaptive angiogenesis in term placental villi from smokers (n=4) and non-smokers (n=4). These images may aid communication of the dangers of smoking in pregnancy.
