Placental morphology: from molecule to mother -- a dedication to Peter Kaufmann -- a review.

abstract：:Recent studies have indicated that oxidative stress is involved in the pathogenesis of pre-eclampsia. Oxidative stress damages systemic tissues, and placental damage may result in intrauterine growth retardation and fetal distress. Thus, this study attempted to elucidate the placental localization of thioredoxin and t...
