Decidua: Anatomy, function and parts - Kenhub
Oct 30, 2023 · The decidua is the modified or specialized mucosal lining of the uterus (endometrium) that forms during the pregnancy. During its formation, the decidua has several distinct parts, named based on the location of each part in relation to the embryo.
Decidua - Wikipedia
The decidua is the modified mucosal lining of the uterus (that is, modified endometrium) that forms every month, in preparation for pregnancy. It is shed off each month when there is no fertilized egg to support. [1] The decidua is under the influence of progesterone. Endometrial cells become highly characteristic.
Decidua definition, layers of decidua, formation & function
Nov 25, 2019 · Decidua is the term for the modified mucosal lining of the uterus (modified endometrium) during a pregnancy, which forms the maternal part of the placenta. Decidua is formed in a process called decidualization under the influence of progesterone.
The decidua—the maternal bed embracing the …
Jun 10, 2016 · The decidua is a transient but important platform in the uterine tissue, which comprises terminally differentiated endometrial stromal cells, newly generated maternal vascular cells, and maternal blood cells inside and outside the vessels.
Decidua - an overview | ScienceDirect Topics
The decidua is a specialised, highly modified endometrium that develops during pregnancy. The decidual reaction is completed only after blastocyst implantation. In the decidua, maternal blood contacts the trophoblast; thus, it is an essential medium for haemochorial placentation and pregnancy success.

The basal plate consists of the syncytiotrophoblast, cytotrophoblast, the compact zone (decidua), and the spongy layer or zone; At the time of delivery, the placenta separates from the uterus at the spongy zone
Placenta - Maternal Decidua - Embryology
6 days ago · The maternal uterine endometrium stromal cells (fibroblast-like) are transformed by steroid hormones (progesterone) and embryonic signals into the decidua. The entire maternal decidua is divided into three regions: decidua basalis, decidua …
Placenta: anatomy and function - Kenhub
Oct 26, 2023 · This surface is composed of the decidua, the modified or specialized endometrium (or mucosal lining of the uterus) that forms in preparation for pregnancy. The decidua has several parts: Decidua basalis - forms the maternal portion of placenta; Decidua capsularis - overlies the embryo; Parietal decidua - the rest of the decidual tissue.
Decidua - an overview | ScienceDirect Topics
The decidua, a specialized tissue layer formed from the endometrium, provides structural and vascular support to the fetus and placenta. The decidua also plays an important immunoregulatory role as it controls the local trafficking and behavior of maternal immune cells in several key ways that contribute to pregnancy success.
Endometrial Decidualization: The Primary Driver of Pregnancy Health
Jun 8, 2020 · The decidua is the maternal tissue most intimately associated with the fetoplacental unit and serves a critical role as an endocrine and immunological organ. The process of implantation/placentation results in the formation of three decidual regions, which are anatomically and functionally distinct.
