title: [Immaturity of syncytial trophoblast in maternal malnutrition. Ultrastructural analysis].
abstract: We studied the placental membrane at term in normal females and females with malnutrition not related to associated pathologic processes of pregnancy. Both groups belonged in the low socioeconomic stratum. The fetal aspect of placenta from malnourished females showed signs of immaturity in relation to gestational age, as evidenced by transitional cytotrophoblastic cells in different stages of maturation. The latter appear as a third intermediata layer between cytothropoblast and syncitiotrophoblast.
