Popis: Fetal overgrowth in diabetic pregnancy (DP) is popularly attributed to hyperinsulinism. However, the roles of other growth-promoting peptides in the mother and the fetus and of their receptors in the placenta remain unclear. We measured at term, concentration and affinity of placental trophoblastic membrane receptors (TR) for insulin (I), IGF-I and IGF-II in 8 DP's (White Class B, 1-dependent) and 8 non-DP's and correlated these with maternal and cord serum IGF-I and IGF-II levels, infant and placenta weights, and maternal body mass index (BMI). DP and non-DP differed significantly in infant weight (g), 4248±114 (M±SEM) vs 3555±119 (P
