title: Placental oxygen consumption. Part II: in vitro studies--a review.
abstract: The human placenta in vivo consumes large amounts of oxygen. After delivery the placenta is exposed to anoxia and under in vitro experimental conditions oxygen consumption is only a fraction of in vivo estimates. In spite of a reduced oxygen supply, structural and functional integrity of the tissue is surprisingly well preserved. Special metabolic adjustments in the sense of 'partial metabolic arrest' may be the explanation for a remarkable survival capacity of placental tissue and reduction of protein synthesis seems to be an important component of metabolic slowdown. The potential significance of this special feature of placental metabolism for the in vivo situation is discussed.
