Placental expression of D-chiro-inositol phosphoglycans in preeclampsia.

abstract：:Early placental development is characterised by rapid cell differentiation and migration, matrix remodelling and angiogenesis. The enzyme NAD(P)H oxidase is a major source of superoxide anions implicated in signalling pathways regulating these processes in other systems. It is also thought to be involved in oxygen sen...
