Trophoblast Development in the Murine Preimplantation Embryo.

abstract：:Estrogens are frequently used in reproductive medicine. The Women's Health Initiative trial found that the risks of menopausal hormone therapy (MHT) exceed the benefits. The estrogens in MHT, however, were introduced prior to our understanding of the mechanism of action of estrogens. Estrogen signaling is highly compl...
