Molecular mechanisms of development of the human fetal female reproductive tract.
Human female reproductive tract development rests mostly upon hematoxilyn and eosin stained sections despite recent advances on molecular mechanisms in mouse studies. We report application of immunohistochemical methods to explore the ontogeny of epithelial and mesenchymal differentiation markers (keratins, homobox proteins, steroid receptors), transcription factors and signaling molecules (TP6...
متن کاملComparative female reproductive tract development and morphology
A brief description of the basic pattern of mammalian organogenesis of the female reproductive tract is presented based on events as they occur in human beings. The emphasis is not on the details of this development, but rather its organization and timing. Tables of comparative development provide a comparison of similar events between man, rat, mouse, and chick.
متن کاملExpression of androgen receptors in upper human fetal reproductive tract.
BACKGROUND Androgens play a key role in human fetal development. All androgens act through a single intracellular androgen receptor (AR), which is encoded by a single copy gene on the X chromosome. ARs are expressed as early as 9 weeks in the epithelium and mesenchyme of the urogenital sinus, paramesonephric (Müllerian) and mesonephric (Wolffian) ducts. METHODS Using immunohistochemistry, we ...
متن کاملWnt-7a maintains appropriate uterine patterning during the development of the mouse female reproductive tract.
The murine female reproductive tract differentiates along the anteroposterior axis during postnatal development. This process is marked by the emergence of distinct cell types in the oviduct, uterus, cervix and vagina and is dependent upon specific mesenchymal-epithelial interactions as demonstrated by earlier heterografting experiments. Members of the Wnt family of signaling molecules have bee...
متن کاملManifestations of immune tolerance in the human female reproductive tract
Like other mucosal surfaces (e.g., the gastrointestinal tract, the respiratory tract), the human female reproductive tract acts as an initial barrier to foreign antigens. In this role, the epithelial surface and subepithelial immune cells must balance protection against pathogenic insults against harmful inflammatory reactions and acceptance of particular foreign antigens. Two common examples o...
