DISCUSSION In this paper is shown that obesity associate with hypertension produce severe degenerative changes in stem villi and other placental villi. Although no thrombosis was observed in stem villi, it could to be possible that obstructive lumina of the vessels in the chorionic plate leads to villous stromal changes in the placental villi or in the syncytio by reduction of blood flow.Hypertension appears to induce vascular endothelial damage. Maternal hypertension predispose to decresead uteroplacental blood flow which could to stimulate few attracting of blood by intermediate placental villi provoking isquemic placental villi with degenerative changes.The underperfusion of the intervillous space has resulted in local areas with increased perivillous fibrin and villous agglutination. Growing evidence in human and animal models of maternal obesity indicate several placental changes: increased idiopathic villitis, macrophage infiltration and placental vascularity9. A reduction of blood flow in ...

Using immunofluoresce microscopy and histology, intervillous surface lining components area fractions were measured in healthy term chorionic plate (CP) (n=7), healthy term placental basal plate (n=11), mild pre-eclamptic (MPE) placental basal plate (n=10) and severe pre-eclamptic (SPE) placental basal plate (n=11). The aims are (1) to examine the effect of pre-eclampsia (PE) and its severity on the basal plate (BP) intervillous surface lining composition and (2) to define the composition of the CP intervillous surface lining. The results show the mean birth weight of the babies in the SPE are significantly lower than in the HC and MPE (F (2, 29) = 11.912, p =0.000) and the mean gestational age at delivery (GAD) in the SPE group is significantly lower than the HC and MPE (GAD) [Anova p = 0.001; posthoc, p =0.003 and p = 0.001 for MPE and healthy control (HC) respectively]. The mean anchoring villi (AV) to fibrin (NS) ratio of the BP intervillous surface lining is significantly lower in the SPE ...

Hello ladies, On my February 2011 birth club (obviously my pregnancy ended in miscarriage), a post about placental location and fetal gender was a hot topic. I thought because we are still in the early stages of pregnancy, I would post this and those who want to update with their results would be fun. ** NOTE: This is considered more of a game. So dont go painting your baby rooms yet :) 97.2% of the male fetuses had a chorionic villi/placenta location on the right side of the uterus. 97.5% of female fetuses had a chorionic villi/placenta location to the left of the uterus. Heres how you read the ultrasound: Tansvaginal ultrasound (Actual result, not a mirror image) If the location of the placenta is on the left of the uterus = girl If the location of the placenta is on the right of the uterus = boy Abdominal ultrasound (Must flip result because it is a mirror image) If the location of the placenta is on the left of the uterus (must flip, its
Our results show that expression and activities of FAO enzymes as well as overall FAO of palmitate and myristate are substantial in human placental villi during gestation and identify trophoblast components as the primary FAO sites in the term placenta. Expression of FAO enzymes and measured activities at lower gestational ages of 12-28 wk are comparable to that in mature slow skeletal muscle, a tissue that uses fatty acids as a substrate to satisfy high energy requirements. The data provide direct evidence that fatty acids undergo extensive mitochondrial β-oxidation in the placenta. Our major conclusion is that fatty acids are utilized as a significant metabolic fuel and energy source in this organ, consistent with our hypothesis. This overall conclusion is novel and at variance with the current concept that glucose is the sole energy source in the placenta (14,16). On the basis of this conclusion, we speculate that human placental mitochondrial FAO is critical for normal growth and maturation ...

Chorionic villus sampling (CVS) is a prenatal test that involves taking a sample of tissue from the placenta, a structure in the uterus that provides blood and nutrients from the mother to the fetus, to test for chromosomal abnormalities and certain other genetic problems.. The chorionic villi are tiny projections of placental tissue that look like fingers and contain the same genetic material as the fetus. Testing may be available for other genetic defects and disorders depending on the family history and availability of lab testing at the time of the procedure.. CVS is usually performed between the 10th and 12th weeks of pregnancy. Unlike amniocentesis (another type of prenatal test), CVS does not provide information on neural tube defects, such as spina bifida. For this reason, women who undergo CVS also need a follow-up blood test between 16 to 18 weeks of their pregnancy to screen for neural tube defects.. There are two types of CVS procedures:. ...

A monoclonal antibody GB25 which was raised against placental syncytiotrophoblast reacted specifically with villous trophoblasts. It recognized syncytiotrophoblast, villous cytotrophoblasts of the first-trimester placentae, and a majority of the cytotrophoblasts in the chorion laeve, but not the residual cells of cytotrophoblastic shell in the basal plates and the cells in the cytotrophoblastic columns. This antibody will be useful for isolating and differentiating villous from extravillous cytotrophoblasts in the first-trimester placentae.
You will take off your clothes below the waist. You will have a paper or cloth covering around your waist. You will lie on your back on an exam table with your feet raised and supported by stirrups.. Your doctor will put a special tool with curved sides (speculum) into your vagina. The speculum gently spreads apart the vaginal walls. This lets the doctor see the inside of the vagina and the cervix. The cervix will be cleaned with a special soap.. Your doctor will use ultrasound to guide a thin tube (catheter) through your cervix to the placenta. Gel will be rubbed on your belly. An ultrasound device (transducer) will be moved over your belly. It gives off and picks up sound waves. The sound waves are sent to a computer to make a picture of your uterus, your baby, and the placenta. The doctor can also use ultrasound to check your babys heart rate. For more information, see the topic Fetal Ultrasound.. When the catheter is in the right place, a sample of chorionic villus cells will be ...
... Some people have basic questions about how pregnancy happens. Some may have questions about avoiding a pregnancy
As a first step to explore the possible relationships existing between the effects of low oxygen pressure in the first trimester placenta and placental pathologies developing from mid-gestation, two subtracted libraries totaling 2304 cDNA clones were constructed. For achieving this, two reciprocal suppressive/subtractive hybridization procedures (SSH) were applied to early (11 weeks) human placental villi after incubation either in normoxic or in hypoxic conditions. The clones from both libraries (1440 hypoxia-specific and 864 normoxia-specific) were spotted on nylon macroarrays. Complex cDNAs probes prepared from placental villi (either from early pregnancy, after hypoxic or normoxic culture conditions, or near term for controls or pathological placentas) were hybridized to the membranes. Three hundred and fifty nine clones presenting a hybridization signal above the background were sequenced and shown to correspond to 276 different genes. Nine of these genes are mitochondrial, while 267 are nuclear.
The cytotrophoblast (or layer of Langhans) is the inner layer of the trophoblast. It is interior to the syncytiotrophoblast and external to the wall of the blastocyst in a developing embryo. The cytotrophoblast is considered to be the trophoblastic stem cell because the layer surrounding the blastocyst remains while daughter cells differentiate and proliferate to function in multiple roles. There are two lineages that cytotrophoblastic cells may differentiate through: fusion and invasive. The fusion lineage yields syncytiotrophoblast and the invasive lineage yields interstitial cytotrophoblast cells. Cytotrophoblastic cells play an important role in the implantation of a newly fertilized egg in the uterus. The formation of all syncytiotrophoblast is from the fusion of two or more cytotrophoblasts via this fusion pathway. This pathway is important because the syncytiotrophoblast plays an important role in fetal-maternal gas exchange, nutrient exchange, and immunological and metabolic functions. ...
Hemochorial placentation, with placental villi bathing in maternal blood, entails direct contact of circulating maternal leukocytes with the fetal trophoblast, ,nobr,i. e.,/nobr, the syncytiotrophoblast, which covers all placental villous trees as well as parts of the inner surfaces of chorionic and basal plates (1). This way, placenta-derived factors, such as hormones and cytokines predominantly released by the syncytio-trophoblast, may influence circulating maternal blood cells and vice versa factors from maternal leukocytes may regulate villous trophoblast functions. Thus, a combination of modulating signals and responses between maternal circulating blood cells and the placental trophoblast may dynamically be adjusted over gestation for an overall cooperative microenvironment in the intervillous space. Alterations in this cooperative microenvironment may occur very early in pregnancy and is suggested to program early placenta functions and growth long before any phenotypic changes become ...
We aimed to investigate the expression of suppressors cytokine signaling (SOCS)-3, transforming growth factor (TGF)-β and indoleamine 2,3-dioxygense (IDO) and to analyse the relationship of SOCS3 and TGF-β with IDO expression in early pregnancy chorionic villi and decidua in the maternal-fetal interface. Western blot analysis and immunohistochemical method were used to detect the expression of TGF-β, SOCS3 and IDO in chorionic villi and decidua tissues of normal pregnant women. SOCS3, TGF-β and IDO protein was identified in chorionic villi and decidua tissues of normal pregnant women and there was a negative correlation between the expression of IDO and SOCS3, but TGF-β expression was positively correlated with IDO expression ...

In this monograph we refer to all varieties of invasive placentation as abnormally adherent placenta. There are 3 commonly defined variants: placenta accreta (where chorionic villi attach to the myometrium, rather than being restricted within the decidua basalis), placenta increta (where the chorionic villi invade into the myometrium), and placenta percreta (where the chorionic villi invade through the myometrium and sometimes into adjoining tissue).

The distribution of mRNAs and antigens of tissue type (t) and urokinase type (u) plasminogen activators (PA) plus their corresponding inhibitors, type-1 (PAI-1) and type-2 (PAI-2) were studied in human and rhesus monkey placentae by in situ hybridisation and immunocytochemistry. Specific monkey cRNA and antibodies against human tPA, uPA, PAI-1 and PAI-2 were used as probes. The following results were obtained. (1) All the molecules tPA, uPA, PAI-1 and PAI-2 and their mRNAs were identified in the majority of the extravillous cytotrophoblast cells of the decidual layer between Rohrs and Nitabuchs striae and in cytotrophoblast cells of the chorionic plate, basal plate, intercotyledonary septae and cytotrophoblast cells of the chorionic villous tree. (2) Expression of uPA and PAI-2 was noted in villous trophoblast whereas tPA and PAI-1 were mainly concentrated where detachment from maternal tissue occurs. (3) No expression of tPA, uPA, PAI-1 and PAI-2 was observed in the basal plate endometrial ...
Term cytotrophoblast do not express polymorphic MHC Class I antigens, unlike other fetal and maternal cells in the amniochorion/decidua. This allows cytotrophoblast to be isolated and purified from this tissue, utilizing 4E, a monoclonal antibody specific for HLA-B, which labels only non-trophoblast. We have developed a method using enzymic dispersion and Percoll gradient centrifugation, followed by flow cytometry, that yields, on average, a total of 5 X 10(6) term extravillous cytotrophoblast, 97 per cent pure. The availability of highly purified extravillous cytotrophoblast, for the first time, permits precise investigation of trophoblast function.

This study was done on 60 pregnant women that have case intra uterine fetal death in kerbala city. We determined the placental abnormalities that lead to intra uterine fetal death through histopathological sections. The resulting shown six groups of cases with defective placental maturation .The first group of cases shown absence of syncytio-vascular membrane formation and the second group shown immaturity and hydropic degeneration of chorionic villi. The third group shownchronic villitis and the fourth shown fibrin depositions and loss of vessels in the villous stroma of placenta .The fifth group shown foetal thrombotic lesions which consist of large groups of vascular fibrotic villi as the result of vessel thrombosis .The last group shown umbilical cord abnormal coiling (over coiling) or under coiling . These groups of cases represent the most important causes of late intra utrine fetal death.

Capillaries in intestinal villi. Light micrograph of a transverse section through villi in the small intestine, showing the blood supply. At bottom are the outer muscle layers in the wall of the small intestine. Villi are finger-like projections on the inner wall, which face the lumen (at top). The villi are adapted for the absorption of digested food. The core of each villus contains blood capillaries (dark), which here have been injected to highlight their structure. Epithelial cells on the surface of each villus absorb food, which is then passed into the bloodstream through this capillary system. The 6 metre long human small intestine contains thousands of villi. - Stock Image P520/0080
These tree-like masses originating from the umbilical cord (and thus fetus) sit in a cavity called the intervillous space, and are bathed in nutrient-rich maternal blood. This maternal blood, which provides the fetus with a means for both nutrient delivery and waste elimination, is continually replenished via a network of maternal arteries and veins that feed into the intervillous space. Furthermore, these arteries and veins help to anchor the placenta into the uterine wall. One of the most interesting aspects about the mother-feus relationship is that the blood vessel connection is indirect. This helps to prevent a detrimental immune response, which could lead to immunological rejection of the fetus (sort of like how a transplanted organ can become rejected by the recipient ...
Hi I feel like I am losing my mind, still waiting for our full CVS (Chorionic Villus Sampling) results and it has been 2 weeks. Just rang the clinic who now said it can be 2 - 3 weeks! Really dont think I can take another week of all this waiting, what can be taking so long, just want to know that all is ok so we can book the heart scan. This is the worst 2 weeks ever. Is anyone else waiting for results? Sam

There, the villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen.[2]. There are also enzymes (enterocyte digestive enzyme) on the surface for digestion. Villus capillaries collect amino acids and simple sugars taken up by the villi into the blood stream. Villus lacteals (lymph capillary) collect absorbed chylomicrons, which are lipoproteins composed of triglycerides, cholesterol and amphipathic proteins, and are taken to the rest of the body through the lymph fluid. Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream. They have a rich blood supply to keep a concentration gradient.[3]. ...
Pregnancy induced hypertension (PIH) is a significant problem in maternal medicine. According to recent publications, insufficient invasion of extravillous trophoblasts into the myometrial parts of the spiral arteries may be responsible for this. The vessel inadequately adapts to the increased perfusion uterus need during pregnancy and consequently, multiple vasodilatory mediators are released. This results in the clinical picture of endothelial dysfunction with hypertension, proteinuria and oedema. The reason of this inadequate invasion of trophoblasts is unknown. In order to identify the causative factors, we hypothesise that the trophoblasts invasion at the beginning of pregnancy is comparable with the growth of malignant tumours.The invasion of extravillous trophoblasts shows a breach of basal membranes and invasive growth. Therefore, growth factors and their receptors, in particular those of the EGF family could play a central role. They have already been researched extensively in relation ...

Some screening tests are done in the first trimester of pregnancy, and some are done in the second trimester. Your doctor may have you tested in both trimesters, depending on your babys risk and the testing method you select.. There are several ways to do the screening. One type of screening (no needles) is an ultrasound. This measures the thickness of the liquid under the skin on your babys neck. If the thickness is not normal, your baby may not have the normal number of chromosomes. Your doctor may also do a blood test to check your babys risk of having a genetic disorder.. There are two tests that can say for sure if your baby has a genetic disorder. They both have a small risk of causing a miscarriage. One test is called amniocentesis (AM-nee-oh-sen-TEE-sis). This is when the doctor uses a needle to take a small sample of fluid from the bag of water around the baby. The other test is called chorionic villus (core-ee-AH-nick VIL-us) sampling. This is when the doctor uses a needle to take a ...

Hi Friederike! We tried a contact with bioinformatics support of Ion, and they told us that we could do it and recommended to separate our reads with samtools. We tried it again, without any success and different suggestion from support. I proceeded to a depth calculation in samtools itself and i cant see the CALCA here. You know, my coverage was not 100%, some reads was lost as machine output shows (60-70% of useful reads) maybe this is just the case. There is no way to recover because (for some reason) the primer, machine or pipeline of the version that we made use failed.. flagstat statistics 5467132 + 0 in total (QC-passed reads + QC-failed reads) 5457323 + 0 mapped (99.82% : N/A).
