Localization of Bradykinin B2Receptors in the Endometrium and Myometrium of Rat Uterus and the Effects of Estrogen and Progesterone1
1999
In the uterus, bradykinin is a potent inducer of smooth muscle contraction, which is mediated by the bradykinin B2 receptor subtype. However, little is known about the distribution or regulation of this receptor in this tissue. The aim of this study was to localize the B2 receptor in the uterus and determine whether the levels of this receptor were altered during the estrous cycle and modulated by estrogen and/or progesterone in ovariectomized rats. At diestrus, uterine B2 receptors were localized to both the circular and longitudinal smooth muscle layers of the myometrium, the endometrial stroma, the glandular epithelium, and the layer subjacent to the luminal epithelium. B2 receptor level…
Molecular investigation on the etiology of preeclampsia and new strategies for its early diagnosis
2023
Endometrial decidualization is critical for pregnancy establishment and maintenance. This process promotes endometrial remodeling allowing placental cytotrophoblasts (CTBs) invasion up to an appropriate depth to form the maternal-fetal interface. A shallow CTBs invasion compromises healthy pregnancy and it is associated with the development of severe preeclampsia (sPE). Our working hypothesis is that defective decidualization impairs the adaptation of the maternal “soil” ─the decidua─ to be invaded by CTBs and plays a pivotal role in the etiology of sPE. Previously, we have demonstrated the existence of an in vitro defective decidualization of endometrial stromal cells isolated from women w…
Identification of new regenerative therapies in reproductive medicine and their application as a future therapeutic approach for endometrial regenera…

El útero es uno de los principales órganos internos del sistema reproductor femenino. Está compuesto de tres capas tisulares: perimetrio, miometrio y endometrio. Esta última capa recubre la cavidad intrauterina y es responsable directa de la implantación embrionaria (para la cual necesita un grosor endometrial mínimo). Entre las patologías que afectan al endometrio pueden distinguirse, entre otras, la atrofia endometrial (insuficiente grosor endometrial) y el síndrome de Asherman (presencia de adhesiones intrauterinas y tejido fibrótico), las cuales conforman el hilo conductor de esta tesis, compuesta de 4 artículos científicos. En ambos casos, el tejido endometrial se encuentra degenerado,…
