Epitheliochorial placenta

Epitheliochorial placentation is a derived condition and has evolved separately in strepsirrhine primates and laurasiatherians (pangolins, whales, and hoofed mammals). Usually it is associated with a long gestation period, small litters, and precocial young. Oxygen transfer is facilitated by indenti epitheliochorial placentation Chorionic villi, growing into the apertures of uterine glands ( epithelium). (e.g. in ruminants , horses , whales , lower primates , dugongs

In the epitheliochorial placenta, the contacting fetal and maternal surfaces at the feto-maternal interface are covered with microvilli, which leads to an increase of membrane surfaces available for transport processes In comparison to the epitheliochorial placenta, the endothelial placenta is slightly less complete in that the maternal epithelial cell layer (endometrial epithelium) and basal laminae are degraded such that the maternal capillaries present in the connective tissue traditionally found behind the basal laminae are in direct contact with the fetal membranes (chorionic epithelium) of the placenta Epitheliochorial Placenta: This type of placenta involves the contact of the chori­onic epithelium with that of uterine epithelium and thus the term epitheliochorial. The epitheliochorial placenta involves six tissue barriers between the foetal and maternal circulation

The placentome consists of cuboidal cells in the uterine epithelium, with large centrally located nuclei overlying the well‐vascularized lamina propria. Although the placentome has a similar cytological structure to that of the omphaloplacenta, granules or active vesicle secretion were not observed The placenta of all camelids is epitheliochorial and non-invasive. Fowler & Olander (1990) considered the focal areas of folded papillation to correspond to placentomes of other species. The amnion closely adheres to the chorion and allantoic sac. Most observers describe an. In epitheliochorial placentation, there are minimal changes in the stroma of the uterine mucosa during pregnancy, apart from local angiogenesis, which is needed to increase the blood flow and deliver nutrients to the uterine surface The cetacean placenta is an epitheliochorial, diffuse organ that implants all over both uterine horns. It fills the entire uterus, with the umbilical cord inserting near the endocervical os. The time of implantation following fertilization is unknown Type of Placenta Common Examples; Diffuse, epitheliochorial: Horses and pigs: Cotyledonary, epitheliochorial: Ruminants (cattle, sheep, goats, deer) Zonary, endotheliochorial: Carnivores (dog, cat, ferret) Discoid, hemochorial: Humans, apes, monkeys and rodent

The evolution of epitheliochorial placentatio

1. The chorioallantoic placenta is diffuse, folded, epitheliochorial, and nondeciduate . The fusiform chorionic sac adheres to the endometrium over its entire area, except at the avascular extremities and over the uterine gland openings, where areola-gland complexes are formed ( Figs. 14-2 , 14-6 , and 14-7 )
2. The equine placenta is anatomically defined as diffuse, microcotyledonary and epitheliochorial. The placenta's functions include exchange of nutrients and gases, and removal of waste materials. Equine placental transfer is inefficient in comparison to other species
3. Related to endotheliochorial placenta: epitheliochorial placenta, hemochorial placenta, syndesmochorial placenta. en·do·the·li·o·cho·ri·al pla·cen·ta. a placenta in which the chorionic tissue penetrates to the endothelium of the maternal blood vessels

The pig has a diffuse epitheliochorial placenta. The foeto-maternal surface area (Sv(F), Sv(M)) is enlarged at three levels: level I: macroscopic folds of uterine mucosa covered by foetal membranes; level II: light microscopic folds of uterine epithelium covered by trophoblastic epithelium; level III: ultrastructural formation of both maternal and foetal microvilli in an interdigitating pattern This may be due to differences in implantation and placentation in pigs, which forms a non-invasive true epitheliochorial type placenta and does not require a decidualization process during the implantation period, whereas in humans and rodents the endometrium is decidualized for implantation and an invasive hemochorial type placenta is formed when the embryo is implanted

Des Weiteren gibt es eine Placenta diffusa (epitheliochorial) bei Unpaarhufern und Walen, eine Placenta zonaria (endotheliochorial) bei Raubtieren, eine Placenta discoidalis (hämochorial) bei Nagetieren und den Trockennasenaffen, einschließlich des Menschen, sowie eine Placenta multiplex s. cotyledonaria oder (syndesmochorial) bei Wiederkäuern The results revealed that trophoblast of epitheliochorial placenta produces simultaneously immuno-stimulatory and -suppressive factors acting across the species barrier. Their presence at the feto-maternal interface may contribute to the regulation of local immune reactions and survival of the allogenic fetuses despite the morphological specificities of this type of placentation Find out information about epitheliochorial placenta.

Evolutionary implications of fetal and maternal

The epitheliochorial and diffuse placenta of strepsirrhine primates are shared derived features that evolved on the strepsirrhine stem lineage. Strepsirrhines and catarrhines (Old World monkeys, apes, and humans) have villous maternofetal interdigitation, but tarsiers and New World monkeys have trabecular interdigitation In epitheliochorial placentation, the maternal epithe-lium is preserved, whereas in the hemotrophic placenta, trophoblast cells invade maternal tissue up to the endo-thelial layer [2]. Therefore, the epitheliochorial placenta is considered a less invasive placenta, because fetal cells do not bypass the endometrial basal membrane [9,10]. Not In the epitheliochorial placenta, the contacting fetal and maternal surfaces at the feto‐maternal interface are covered with microvilli, which leads to an increase of membrane surfaces available for transport processes

tially invasive endotheliochorial placentas, only the endothelial wall of the maternal blood vessels separates the fetus from the maternal blood (3). Epitheliochorial placentas, the least invasive, have three layers of maternal tissue separating the fetus from maternal blood. Classically, invasive hemochorial placentatio Mammalian placentas can be classified based on the number of tissues separating the maternal from the fetal blood. These include: endotheliochorial placentation In this type of placentation, the chorionic villi are in contact with the endothelium of maternal blood vessels. (e.g. in most carnivores like cats and dogs) epitheliochorial placentatio epitheliochorial, and non-infectious causes of miscarriage, like placental edema and development of twins. 3 Figur 1.

4. Moreover, the non-invasive epitheliochorial placentation appears to be a derived trait that evolved several times independently in eutherian mammals from more invasive placental types (hemochorial or endotheliochorial) [10-12].

5. The epitheliochorial placenta is the simplest type with all six tissue barriers present and is the most primitive type. The immediate contact of the two halves of the placenta involves chorionic epithelium and uterine epithelium. E.g., pigs, lemurs.

(epitheliochorial placenta anlamı, epitheliochorial placenta Türkçesi, epitheliochorial placenta nnd The ability of the placenta to transfer various substances differs among species. The markedly thicker epitheliochorial placenta found in sheep, a species commonly used for placental transfer studies, has three maternal layers (epithelium, connective tissue, and endothelium) that separate maternal from fetal blood (2004) Carter, Enders. Reproductive Biology and Endocrinology. Based on the number of tissues separating maternal from fetal blood, placentas are classified as epitheliochorial, endotheliochorial or hemochorial. We review the occurrence of these placental types in the various orders of eutherian.

Uteroplacental tissue plays a key role in substance exchanges between maternal and fetal circulation, and, therefore, in the growth and development of fetuses. In this study, proteomics and western blotting were applied to investigate the changes of proteome in the placenta and endometrium of normal and intrauterine growth restriction (IUGR) porcine fetuses during mid to late pregnancy (D60. The non-invasive trophoblast of the allantochorion establishes a stable microvillous contact with the endometrial epithelium around Day 40 and, over the next 100 days, develops a complex multibranched interdigitation with the endometrium to form the microcotyledonary haemotrophic exchange units that cover the entire surface of the diffuse epitheliochorial placenta placenta [ANAT.] der Mutterkuchen Pl.: die Mutterkuchen placenta [ANAT.] [BOT.] die Plazenta auch: Placenta Pl.: die Plazenten/die Plazentas placenta [MED.] die Nachgeburt Pl.: die Nachgeburten chorionic placenta [MED.] die Chorionplazenta Pl.: die Chorionplazenten/die Chorionplazentas - Embryologie villous placenta [MED. The site of gaseous and nutrient exchange is therefore between two microvasculatures and, because of the greater resistance inherent in this anatomical arrangement and an increase in the number of cell layers (4 to 6) separating the two circulations, the inflow pressure to an epitheliochorial placenta is significantly higher than that of a hemochorial placenta, e.g., >80 mmHg in the ewe
