What is implantation or decidualization?
Once implantation occurs and the embryo breaches the luminal epithelium, the stromal cells surrounding the implanting embryo transform into a decidua by a process called decidualization [9,95].
What is the purpose of decidualization?
Decidualization plays an important role in promoting placenta formation between a mother and her fetus by mediating the invasiveness of trophoblast cells. It also triggers the production of cellular and molecular factors that result in structural changes, or remodeling, of maternal spiral arteries.
What is Desidual?
Anatomical terminology. The decidua is the modified mucosal lining of the uterus (that is, modified endometrium) that forms in preparation for pregnancy. It is formed in a process called decidualization under the influence of progesterone. Endometrial cells become highly characteristic.
What is uterine decidualization?
Decidualization refers to the functional and morphological changes that occur within the endometrium to form the decidual lining into which the blastocyst implants. These changes include the recruitment of leukocytes and, importantly, the differentiation of endometrial stromal fibroblast cells (ESCs) into DSCs.
What is Decidualized endometriosis?
Decidualized endometriosis is a benign condition associated with ectopic endometrial tissue that has undergone a decidual reaction during pregnancy.
What does thick uterus wall mean?
Endometrial hyperplasia is a condition of the female reproductive system. The lining of the uterus (endometrium) becomes unusually thick because of having too many cells (hyperplasia). It’s not cancer, but in certain women, it raises the risk of developing endometrial cancer, a type of uterine cancer.
What is Parietalis?
n. The mucous membrane lining the main cavity of the pregnant uterus elsewhere than at the site of attachment of the chorionic vesicle. decidua vera.
What is good decidual reaction in pregnancy?
A decidual reaction is a feature seen in very early pregnancy where there is thickening of the endometrium around the gestational sac. A thin decidual reaction of less than 2 mm is considered one of the features suggestive of an anembryonic pregnancy 2.
What is Decidual Basalis?
Dictionary Entries Near decidua basalis Accessed 24 Nov. 2021. Style: MLA.
Which is the best definition of decidualization?
The condition of being decidualized; the process by which decidua is formed from endometrium. 1920s. From decidual + -ization.
What is the role of decidualization in the fetus?
Decidualization plays an important role in promoting placenta formation between a mother and her fetus by mediating the invasiveness of trophoblast cells. It also triggers the production of cellular and molecular factors that result in structural changes, or remodeling, of maternal spiral arteries.
How is the decidua process linked to premature birth?
Chronic deciduitis, a chronic inflammation of the decidua, has been linked with premature birth. The decidualization process is initiated by progesterone, but this requires cyclic adenosine monophosphate (cAMP) to act as the initial signalling molecule to sensitize endometrial cells to progesterone.
Where does the decidualization of the endometrium occur?
Changes also occur in the stromal cells, which undergo a characteristic decidualization reaction. Decidualized stromal cells are derived from the fibroblast-like cells within the endometrium, which maintain their progesterone receptors in the presence of progesterone.
