Estrogens are important for normal bone growth and metabolism. The mechanisms are incompletely understood. Thus, we have undertaken characterization of the skeletal phenotype of aromatase (ArKO) deficient mice. No abnormalities have been noted in skeletal patterning in newborns. Adult ArKO mice show decreased femur length and decreased peak Bone Mineral(More)
Endothelin-1 (ET-1) mRNA is expressed by the human placenta in a developmentally regulated manner and has been shown to stimulate the growth of placental mesenchymal cells. The ability of placental fibroblasts to express preproET-1 mRNA was studied to determine if ET-1 could potentially participate via autocrine mechanisms in the proliferation of placental(More)
Preterm, human, placental fibroblasts exhibit growth rates, in vitro, that vary with gestational age. The observed increase in proliferation rate is associated with enhanced mitogenic responsiveness to IGF-I. IGFBPs can either potentiate or inhibit IGF action at the cellular level. The production of IGFBPs by placental fibroblasts was studied as potential(More)
