Placental insulin and insulin-like growth factor I receptors in normal and preeclamptic pregnancies

These data demonstrate that preeclampsia is associated with low placental IR affinity. In addition, this study suggests an association between the affinity of IR and number of IGF-1R with placental and/or fetal growth. Furthermore, high blood pressure may affect the affinity of placental IR, but not the affinity or number of placental IGF-1 receptors.
