Amnion
The innermost membranous sac that surrounds and protects the developing embryo which is bathed in the AMNIOTIC FLUID. Amnion cells are secretory EPITHELIAL CELLS and contribute to the amniotic fluid.
Extraembryonic Membranes
The thin layers of tissue that surround the developing embryo. There are four extra-embryonic membranes commonly found in VERTEBRATES, such as REPTILES; BIRDS; and MAMMALS. They are the YOLK SAC, the ALLANTOIS, the AMNION, and the CHORION. These membranes provide protection and means to transport nutrients and wastes.
Chorion
The outermost extra-embryonic membrane surrounding the developing embryo. In REPTILES and BIRDS, it adheres to the shell and allows exchange of gases between the egg and its environment. In MAMMALS, the chorion evolves into the fetal contribution of the PLACENTA.
Labor, Obstetric
The repetitive uterine contraction during childbirth which is associated with the progressive dilation of the uterine cervix (CERVIX UTERI). Successful labor results in the expulsion of the FETUS and PLACENTA. Obstetric labor can be spontaneous or induced (LABOR, INDUCED).
Amniotic Fluid
A clear, yellowish liquid that envelopes the FETUS inside the sac of AMNION. In the first trimester, it is likely a transudate of maternal or fetal plasma. In the second trimester, amniotic fluid derives primarily from fetal lung and kidney. Cells or substances in this fluid can be removed for prenatal diagnostic tests (AMNIOCENTESIS).
Parturition
The process of giving birth to one or more offspring.
Pregnancy
The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.
Amniotic Band Syndrome
A disorder present in the newborn infant in which constriction rings or bands, causing soft tissue depressions, encircle digits, extremities, or limbs and sometimes the neck, thorax, or abdomen. They may be associated with intrauterine amputations.
Decidua
The hormone-responsive glandular layer of ENDOMETRIUM that sloughs off at each menstrual flow (decidua menstrualis) or at the termination of pregnancy. During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.
Placenta
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
Labor Onset
The beginning of true OBSTETRIC LABOR which is characterized by the cyclic uterine contractions of increasing frequency, duration, and strength causing CERVICAL DILATATION to begin (LABOR STAGE, FIRST ).
Fetal Membranes, Premature Rupture
Spontaneous tearing of the membranes surrounding the FETUS any time before the onset of OBSTETRIC LABOR. Preterm PROM is membrane rupture before 37 weeks of GESTATION.
Serous Membrane
A thin lining of closed cavities of the body, consisting of a single layer of squamous epithelial cells (MESOTHELIUM) resting on a thin layer of CONNECTIVE TISSUE, and covered with secreted clear fluid from blood and lymph vessels. Major serous membranes in the body include PERICARDIUM; PERITONEUM; and PLEURA.
Cellulose, Oxidized
A cellulose of varied carboxyl content retaining the fibrous structure. It is commonly used as a local hemostatic and as a matrix for normal blood coagulation.
Reptiles
Cold-blooded, air-breathing VERTEBRATES belonging to the class Reptilia, usually covered with external scales or bony plates.
Chorionic Villi Sampling
A method for diagnosis of fetal diseases by sampling the cells of the placental chorionic villi for DNA analysis, presence of bacteria, concentration of metabolites, etc. The advantage over amniocentesis is that the procedure can be carried out in the first trimester.
Limb Deformities, Congenital
Congenital structural deformities of the upper and lower extremities collectively or unspecified.
Birds
Warm-blooded VERTEBRATES possessing FEATHERS and belonging to the class Aves.
Natural Childbirth
Labor and delivery without medical intervention, usually involving RELAXATION THERAPY.
Genetics, Medical
A subdiscipline of human genetics which entails the reliable prediction of certain human disorders as a function of the lineage and/or genetic makeup of an individual or of any two parents or potential parents.
Genetic Counseling
An educational process that provides information and advice to individuals or families about a genetic condition that may affect them. The purpose is to help individuals make informed decisions about marriage, reproduction, and other health management issues based on information about the genetic disease, the available diagnostic tests, and management programs. Psychosocial support is usually offered.
Genetic Diseases, Inborn
Diseases that are caused by genetic mutations present during embryo or fetal development, although they may be observed later in life. The mutations may be inherited from a parent's genome or they may be acquired in utero.
Genetic Testing
Detection of a MUTATION; GENOTYPE; KARYOTYPE; or specific ALLELES associated with genetic traits, heritable diseases, or predisposition to a disease, or that may lead to the disease in descendants. It includes prenatal genetic testing.
Dexmedetomidine
A imidazole derivative that is an agonist of ADRENERGIC ALPHA-2 RECEPTORS. It is closely-related to MEDETOMIDINE, which is the racemic form of this compound.
Medetomidine
An agonist of RECEPTORS, ADRENERGIC ALPHA-2 that is used in veterinary medicine for its analgesic and sedative properties. It is the racemate of DEXMEDETOMIDINE.
Rhytidoplasty
Plastic surgery performed, usually by excision of skin, for the elimination of wrinkles from the skin.
Chiroptera
Order of mammals whose members are adapted for flight. It includes bats, flying foxes, and fruit bats.
Rabies
Acute VIRAL CNS INFECTION affecting mammals, including humans. It is caused by RABIES VIRUS and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals. Important animal vectors include the dog, cat, bat, fox, raccoon, skunk, and wolf.
Rabies virus
The type species of LYSSAVIRUS causing rabies in humans and other animals. Transmission is mostly by animal bites through saliva. The virus is neurotropic multiplying in neurons and myotubes of vertebrates.

Prostaglandin endoperoxide H synthase mRNA expression in the human amnion and decidua during pregnancy and in the amnion at preterm labour. (1/868)

We have examined the expression of prostaglandin endoperoxide H synthase (PGHS) isoenzymes in the amnion and the decidua during gestation, and the abundance of PGHS mRNA in the amnion at idiopathic preterm labour. PGHS-1 and -2 mRNA abundance in the amnion, determined with ribonuclease protection assays, was significantly (P< 0.05) higher at term than earlier during pregnancy. In contrast, neither PGHS-1 and -2 mRNA values, nor PGHS-specific activity, measured with a cell-free assay, was different in the decidua at term as compared to earlier gestational ages. In individual term patients, PGHS-2 mRNA values in the amnion were positively correlated with PGHS-2 mRNA values in the chorion laeve. PGHS-1 and -2 mRNA abundance was higher (P < 0.05) in the amnion after idiopathic preterm labour than in the absence of labour at the same gestational age (28-35 weeks). Thus, PGHS-1 and -2 are induced in the amnion at term. Furthermore, amniotic PGHS-2 changes in co-ordination with PGHS-2 concentrations in the chorion laeve. PGHS is not induced in the decidua at term. Increased amniotic PGHS expression may contribute to the enhanced intrauterine prostaglandin synthesis before term labour. Both PGHS isoenzymes may participate in the increase of PGHS activity in the amnion at preterm birth.  (+info)

First-trimester cord entanglement in monoamniotic twins. (2/868)

OBJECTIVE: Monoamniotic twinning occurs in only 1% of twin pregnancies, but carries a high perinatal mortality rate. Early and reliable diagnosis is essential if attempts are to be made to reduce the complication rate. We report color Doppler demonstration of cord entanglement in the first trimester, which is diagnostic of monoamnionicity. METHODS: Two patients with twin pregnancies were examined in the first trimester with pulsed and color Doppler insonation of their umbilical arteries. RESULTS: Cord entanglement was suspected and proved by demonstrating differing fetal heart rate patterns in the same direction on umbilical artery Doppler analysis of a common mass of cord vessels. Following appropriate counselling, medical amnioreduction was induced at 20 weeks of gestation to reduce fetal movements and worsening cord entanglement. Delivery was by elective Cesarean section at 32 weeks' gestation and monoamnionicity was confirmed. CONCLUSION: We report a new sign for the demonstration of monoamnionicity in twin pregnancies in the first trimester. This should improve the reliability of early diagnosis, but further studies are required to confirm that, if cord entanglement occurs, it is usually present by the end of the first trimester.  (+info)

Tissue plasminogen activator and its receptor in the human amnion, chorion, and decidua at preterm and term. (3/868)

The plasminogen activator system consists of two proteins: tissue plasminogen activator (tPA) and urokinase plasminogen activator (uPA), which act upon their specific receptors to generate plasmin from plasminogen located on the cell surface. Plasmin then acts directly and indirectly to degrade the components of the extracellular matrix (ECM). This process is likely to be important in the normal turnover of the ECM of fetal membranes and in its premature weakening in preterm premature rupture of the fetal membranes. Quantitative Northern analysis and in situ hybridization have shown that the decidua expresses mRNA for tPA. However, the immunolocalized tPA protein was most strongly associated with the amnion and chorion, as was its receptor annexin II, suggesting that the amnion and chorion are the targets for decidual tPA. At term, decidual tPA expression was unaffected by labor, and the tPA receptor was elevated both before and after labor. At preterm, the converse was found: decidual tPA expression was significantly (p < 0. 05) up-regulated by labor, but the tPA receptor was not. The results suggest that the generation of plasmin at term would be controlled by an increased concentration of the tPA receptor in the amnion and chorion, whereas at preterm a pathological increase in plasmin would be generated by an overexpression of tPA, initiated by labor.  (+info)

Conjunctival epithelial cell differentiation on amniotic membrane. (4/868)

PURPOSE: Amniotic membrane (AM)-reconstructed conjunctival surfaces recover the normal epithelial phenotype with a significantly higher cell density than the control. The present study was undertaken to examine how AM modulates rabbit conjunctival epithelial cell differentiation. METHODS: Rabbit conjunctival epithelial cells (RCEs) were cultured on the basement membrane side of dispase-pretreated AM, with or without seeding rabbit conjunctival fibroblasts (RCFs) on the stromal side. After 7 to 12 days, half of the cultures were raised to the air-liquid interface, and the remainder stayed submerged. A small group of air-lifted cultures containing RCFs was treated with retinoic acid. After 1, 2, and 4 weeks, cultures were terminated and processed for immunostaining with antibodies directed against distinct types of mucins (SMC and AM3), glycocalyx (AMEM2), keratin K3 (AE5), and K12 (AK2). Additionally, western blot analysis was performed for K3 keratin expression. Ultrastructural changes were evaluated by transmission electron microscopy. RESULTS: In general, RCEs grown on AM were uniformly small, negative to AE5 and AK2 antibodies, and positive to AMEM2 and ASPG1 antibodies. Epithelial stratification and cell polarity with prominent microvilli, tight junctions, and hemidesmosomes were more pronounced in air-lifted cultures. RCEs cocultured with RCFs showed scattered AM3-positive goblet cells, which were not increased by retinoic acid. CONCLUSIONS: RCEs cultured on AM primarily exhibit a nongoblet conjunctival epithelial phenotype. Epithelial stratification and cell polarity, features essential for epithelial differentiation, are promoted by air-lifting. This culture model will be useful for studying how growth and differentiation of conjunctival epithelial cells can be modulated further.  (+info)

Expression of cyclo-oxygenase types-1 and -2 in human fetal membranes throughout pregnancy. (5/868)

Human labour is associated with increased prostaglandin synthesis within the fetal membranes. We have studied the expression of the two isoforms of the central prostaglandin synthetic enzyme, cyclo-oxygenase (COX-1 and COX-2), in human fetal membranes throughout pregnancy, at mRNA, protein and activity levels. COX-1 mRNA expression was low in human amnion and chorion-decidua and did not change with gestational age. COX-2 mRNA expression in fetal membranes increased with gestational age, with significant up-regulation prior to the onset of labour and in association with labour. Protein concentrations of COX-1 did not change, whilst concentrations of COX-2 increased from the first to the third trimester. COX activity increased with gestational age and in association with labour, although prostaglandin production in fetal membranes collected after labour was reduced, suggesting reduced substrate supply. These data suggest that it is up-regulation of COX-2, rather than of COX-1, which mediates increased prostaglandin synthesis within the fetal membranes at term. Much of the increase in COX-2 expression precedes the onset of labour, suggesting that it is a cause, rather than a consequence, of labour.  (+info)

Amnion-derived cells express intercellular adhesion molecule-1: regulation by cytokines. (6/868)

We have examined the expression of the intercellular adhesion molecule-1 (ICAM-1) mRNA in primary and established amnion-derived cell cultures and regulation of this expression by tumour necrosis factor-alpha (TNF-alpha) and interleukin (IL)-1beta. TNF-alpha (50 ng/ml) and IL-1beta (1.0 ng/ml) induced 18- and 11-fold increases respectively in expression of the ICAM-1 mRNA in WISH cells (an amnion epithelium-derived cell line). The increase was detectable within one hour of treatment and peaked by two hours. The protein synthesis inhibitor, cycloheximide (10 microg/ml) did not inhibit this induction. Increased levels of ICAM-1 protein were detected in the cells within 4 h after initiation of treatment with either cytokine. By 16 h of treatment with IL-1beta or TNF-alpha ICAM-1 reached 40 and 73 pg/microg cellular protein, representing 6- and 11-fold stimulations respectively. In primary amnion cells, basal expression of ICAM-1 mRNA was undetectable. However, TNF-alpha (50 ng/ml) induced ICAM-1 mRNA within two hours, peak expression being reached between four and eight hours after initiation of treatment. The present report demonstrates for the first time that amnion derived cells can express ICAM-1 and, further, that this expression is regulated by pro-inflammatory cytokines. This has implications for the amnion as a possible source for soluble ICAM-1, for this gene product as a marker for preterm labour, and for participation of the amnion, additional to its reported secretory role, in inflammatory processes of the fetal membranes.  (+info)

Oxytocin receptor expression in human term and preterm gestational tissues prior to and following the onset of labour. (7/868)

Oxytocin receptor (OTR) mRNA expression has previously been demonstrated in human myometrium, decidua, chorion and amnion but the effect of gestational age and the onset of labour has not been determined in these individual tissues. Spatial OTR mRNA expression was examined by in situ hybridization and ligand binding was confirmed using autoradiography with the iodinated oxytocin antagonist d(CH2)5[Tyr(Me)2,Thr4,Tyr-NH29]-vasotocin (125I-OTA). Tissue was collected at term (>37 weeks of gestation) or preterm (24-36 weeks of gestation) caesarean section and classified as labour (contractions every 5 min associated with cervical dilatation) or non-labour. OTR mRNA expression was measured as optical density units from autoradiographs. There was a highly significant (P<0.001) effect of tissue type on expression of OTR mRNA with expression greatest in myometrium, low in decidua and chorion and not detected in placenta. Similar results were obtained with the 125I-OTA-binding studies, indicating that the message was translated. Amnion had an apparently high level of both hybridization and 125I-OTA binding in some samples, but a lack of specificity prevented quantification of the signal in this tissue type. Term myometrium (labour and non-labour) had significantly higher (P<0.01) OTR mRNA expression than preterm myometrium, but there was no further increase in mRNA concentration associated with labour onset. In contrast, 125I-OTA binding in myometrium was already high at 33 weeks and did not increase further either later in pregnancy or with labour. In decidua there was no effect of gestational age or labour onset on OTR mRNA expression or 125I-OTA binding. In summary, OTR mRNA expression in the myometrium increased in late pregnancy whereas decidual expression was much lower and did not rise at term.  (+info)

Human RNA-specific adenosine deaminase ADAR1 transcripts possess alternative exon 1 structures that initiate from different promoters, one constitutively active and the other interferon inducible. (8/868)

RNA-specific adenosine deaminase (ADAR1) catalyzes the deamination of adenosine to inosine in viral and cellular RNAs. Two size forms of the ADAR1 editing enzyme are known, an IFN-inducible approximately 150-kDa protein and a constitutively expressed N-terminally truncated approximately 110-kDa protein. We have now identified alternative exon 1 structures of human ADAR1 transcripts that initiate from unique promoters, one constitutively expressed and the other IFN inducible. Cloning and sequence analyses of 5'-rapid amplification of cDNA ends (RACE) cDNAs from human placenta established a linkage between exon 2 of ADAR1 and two alternative exon 1 structures, designated herein as exon 1A and exon 1B. Analysis of RNA isolated from untreated and IFN-treated human amnion cells demonstrated that exon 1B-exon 2 transcripts were synthesized in the absence of IFN and were not significantly altered in amount by IFN treatment. By contrast, exon 1A-exon 2 transcripts were IFN inducible. Transient transfection analysis with reporter constructs led to the identification of two functional promoters, designated PC and PI. Exon 1B transcripts were initiated from the PC promoter whose activity in transient transfection reporter assays was not increased by IFN treatment. The 107-nt exon 1B mapped 14.5 kb upstream of exon 2. The 201-nt exon 1A that mapped 5.4 kb upstream of exon 2 was initiated from the interferon-inducible PI promoter. These results suggest that two promoters, one IFN inducible and the other not, initiate transcription of the ADAR1 gene, and that alternative splicing of unique exon 1 structures to a common exon 2 junction generates RNA transcripts with the deduced coding capacity for either the constitutively expressed approximately 110-kDa ADAR1 protein (exon 1B) or the interferon-induced approximately 150-kDa ADAR1 protein (exon 1A).  (+info)

AU - Bhonde, R.. PY - 2012/10. Y1 - 2012/10. N2 - One of the most pressing problems in injury is wound healing and blood vessel formation. The amniotic membrane is important in clinical applications as it is pro-angiogenic, anti-fibrotic and anti-scarring and has low immunogenicity. In this study, we characterized amniotic membrane mesenchymal stem cells (AMMSCs) by their trademark mesenchymal stem cell (MSC) signature and profiled for embryonic pluripotency markers namely alkaline phosphatase, Oct4, Sox2, Nanog, SSEA3 and 4, and Klf4 by RT-PCR and nuclear localization of Oct4 and Nanog by immunocytochemistry. The amnion, although avascular, contains pro-angiogenic factors such as type I, III, IV and V collagen, laminin, and fibronectin in the extra cellular matrix. We, therefore, hypothesized that AMMSCs is ...

Amniotic Membrane Transplant - EyeWikiAmniotic Membrane Transplant - EyeWiki
Amniotic membrane, or amnion, is the innermost layer of the placenta and consists of a thick basement membrane and an avascular stromal matrix. Amniotic membrane transplantation has been used as a graft or as a dressing in different surgical subspecialties. In the field of ophthalmology, it is used broadly 1) to reconstruct the ocular surface after various procedures; 2) as a graft for ocular surface melts; and 3) as a bandage to promote healing in cases of persistent epithelial defects or ocular surface inflammation.

The Use of Hypothermically Stored Amniotic Membrane for Cartilage Repair: A Sheep StudyThe Use of Hypothermically Stored Amniotic Membrane for Cartilage Repair: A Sheep Study
Objective: To evaluate the use of hypothermically stored human amniotic membrane for cartilage repair in adult sheep. Studies show that human amniotic membrane contains pluripotent mesenchymal stem cells that can be influenced to produce chondrocytes. It is unknown if human amniotic cells can produce hyaline-like cartilage. This study evaluates the use of hypothermically stored amniotic membrane (HSAM) to fill chondral defects in a sheep model. We hypothesized HSAM would fill defects with hyaline-like cartilage with chondrocytes populating the matrix. One sheep was used as a control, and four sheep received amniotic membrane. Two of these sheep were used as a normal control comparison. A 1 cm2 defect was created on the trochlear grove in all specimens. Each membrane was sized and laid over with the stromal layer facing the subchondral bone and covered with Fibrin sealant. The knees were harvested at five months and underwent morphological, histological, and immunohistological evaluation based on the

A reconstituted collagen membrane from human amnion has been investigated as a source of collagen matrix, which could be used as a substratum for culturing human fibroblasts. The suitability of pepsin-solubilized reconstituted human amniotic membrane, before and after cross-linking with chitosan, as a dermal matrix for culturing fibroblast was assessed by morphologic, physicochemical, cytotoxic and histochemical methods. Measurement of thermodynamic behaviour, by differential scanning calorimetric (DSC) and thermogravimetric analysis (TGA), and tensile strength suggested that the cross-linked membrane had sufficient elasticity to serve as an efficient dermal substrate for in vitro culture of fibroblasts. Fibroblasts cultured on the chitosan cross-linked collagen membrane had good adherence, retaining their morphology as indicated by microscopic analysis. Proliferation of fibroblasts, observed on this membrane affirms its non-toxic nature. These results support the application of reconstituted ...

Increasing evidence has shown that mesenchymal stem cells (MSCs) yield a favorable therapeutic benefit for thermal burn skin wounds. Human amniotic MSCs (hAMSCs) derived from amniotic membrane have multilineage differentiation, immunosuppressive, and anti-inflammatory potential which makes them suitable for treating skin wounds. However, the exact effects of hAMSCs on the healing of thermal burn skin wounds and their potential mechanisms are not explored. hAMSCs were isolated from amniotic membrane and characterized by RT-PCR, flow cytometry, immunofluorescence, and tumorigenicity test. We assessed the effects of hAMSCs and hAMSC conditional medium (CM) on wound healing in a deep second-degree burn injury model of mice. We then investigated the biological effects of hAMSCs and hAMSC-CM on the apoptosis and proliferation of heat stress-injured human keratinocytes HaCAT and dermal fibroblasts (DFL) both in vivo and in vitro. Next, we explored the underlying mechanisms by assessing PI3K/AKT and GSK3β/β

Wound healing is a complex pathophysiological process that involves a variety of cells and cytokines. In this study, we found that local injection of human amnion mesenchymal stem cells into wounds in rats could promote wound healing. Therefore, we hypothesized that the exosomes of human amnion mesenchymal stem cells contain substances that regulate the migration of epidermal cells. It has been reported that miR-135a is involved in cell migration and transformation. However, there have been no reports of its function in skin wound healing. To test this hypothesis, we injected exosomes overexpressing miR-135a directly into the wound margin. In addition, we tested the migration of BJ cells with overexpression or knockdown of miR-135a in vitro. Additionally, Western blot analysis was used to detect the expression of fibroblast migration-associated proteins after treatment with miR-135a overexpression or knockdown. MiR-135a significantly promoted wound healing compared to the control treatment. Western blot

Results Culture-expanded amnion-derived adherent cells expressed mesenchymal stem cell markers and HLA-ABC molecules and could differentiate into osteoblasts, adipocytes and chondrocyte-like cells, indicating that the cells have the characteristics of mesenchymal stem cells. The Lin-CD34+ cells purified from the frozen umbilical cord blood were strongly positive for HLA-ABC, and contained a large number of hematopoietic stem cells. When the Lin-CD34+ cells were cultured on the autologous (MHC-matched) or MHC-mismatched amnion-derived adherent cells in short-term assays (hematopoietic stem cell-proliferation) and long-term culture-initiating cell assays, greater expansion of the Lin-CD34+ cells was observed in the MHC-matched combination than in MHC-mismatched combinations. The concentration of granulocyte-macrophage colony-stimulating factor in the culture supernatants of the long-term culture-initiating cell assays was significantly higher in the MHC-matched combination than in MHC-mismatched ...

Maternal immunoglobulin-G (IgG) is known to be transported across the placental syncytiotrophoblast during the period when the human fetus is incapable of manufacturing these defensive molecules. In this study we investigated the possible role of the amniochorion, that surrounds the amniotic cavity in which the fetus lies, in the transfer of immunoglobulin. Endogenous IgG was localised in the amniochorion by confocal immunofluorescence microscopy and by ultrastructural labelling of ultrathin frozen tissue sections using the protein A-gold technique. Immunoreactivity was identified in the extracellular matrix tissues and necrotic amniotic epithelial cells. Healthy amniotic epithelial cells and cytotrophoblast cells of the chorion laeve were devoid of endogenous IgG. These results suggest a possible nonspecific paracellular transport pathway between cytotrophoblast cells, which may conceivably contribute to the acquisition of passive immunity by the fetus, and offer a rational explanation for the ...

Shortly after the establishment of the circulation of the yolk-sac the folds of the amnion meet and coalesce above the embryo (Fig. 114, 3 and 4, am). After this the inner or true amnion becomes severed from the outer or false amnion, though the two sometimes remain connected by a narrow stalk. The space between the true and false amnion is a continuation of the body cavity. The true amnion consists of a layer of epiblastic epithelium and generally also of somatic mesoblast, while the false amnion consists as a rule of epiblast only; though it is possible that in some cases (the rabbit ?) the mesoblast may be continued along its inner face. Before the two limbs of the amnion are completely severed the epiblast of the umbilical vesicle becomes separated from the subjacent mesoblast and hypoblast of the vesicle (Fig. 114, 3), and, together with the false amnion (sh) with which it is continuous, forms a complete lining for the inner face of the zona radiata. The space between this membrane and the ...

The basic helix-loop-helix (bHLH) transcription factor, Hand1, plays an important role in the development of the murine extra-embryonic trophoblast cell lineage. In the present study, we have analysed the expression of Hand1 in human extra-embryonic cell types and determined its binding specificity and transcriptional activity upon interaction with different class A bHLH factors. Northern blotting and in situ hybridization showed that Hand1 mRNA is specifically expressed in amnion cells at different stages of gestation. Accordingly, we demonstrate that the protein is exclusively produced in the amniotic epithelium in vivo and in purified amnion cells in vitro using a novel polyclonal Hand1 antiserum. Reverse transcriptase-PCR and immunohistochemical staining of blastocysts revealed the production of Hand1 mRNA and polypeptide in the trophectodermal cell layer. In the presence of E12/E47, Hand1 stimulated the transcription of luciferase reporters harbouring degenerate E-boxes, suggesting that ...

Abstract: The purpose of this study was to investigate the relationship between cell apoptosis and wide-band electromagnetic pulse (WEMP) irradiation parameters and to provide experimental data to establish the biophysics damage model for WEMP. Cell counting kit-8 was used to detect the cell viability changes after WEMP irradiation and flow cytometry assay was used to detect cell apoptosis after irradiation under different WEMP irradiation parameters. Under experimental conditions, field strength and number of pulses were observed to be the main factors that increased the apoptotic rate of human amniotic epithelial cells. Specifically, electric field intensity and number of pulses were determined to be the primary and secondary factors, respectively. The two factors were confirmed to interact with each other, that is, a logistic function was found to exist between the apoptotic rate and electric field strength..

ABSTRACT BACKGROUND: The human placenta-derived amniotic mesenchymal stem cells (hAMSCs) exhibit immunomodulatory, partially pluripotent, and precardiac properties. They express the c-kit cardiac progenitor marker and are readily reprogrammed to iPSCs (MiPSCs). Dual contrast manganese-enhanced MRI (MEMRI) and delayed enhancement MRI (DEMRI) has been developed to evaluate the cardiac restorative effects of hAMSCs, c-kit+ hAMSCs, and MiPSCs.. HYPOTHESIS: MEMRI and DEMRI will identify the mechanism of myocardial restoration.. METHODS: SCID-beige mice underwent LAD ligation and received 250,000 cells or normal saline (NS) in the peri-infarct region. The mice were divided into 4 arms: (1) NS (control group, n=7), (2) hAMSC (n=6), (3) c-kit+ hAMSC group (n=2), and (4) MiPSC group (n=3). The hAMSCs were transfected with a luciferase reporter gene. Cardiac MRI measured the scar, viable myocardium, and LVEF at weeks 1, 2, and 4. Bioluminescence imaging (BLI) was also performed and blood was drawn at week ...

One of the most established roles of oxytocin (OT) is in inducing uterine contractions and labour. Apart from contractions, our recent study have shown that OT can also activate pro-inflammatory pathways in both human myometrial and amnion cells which suggests the pro-inflammatory role of OT should be taken into account when developing tocolytics targeting the OT/OT receptor (OT/OTR) system. The OTR antagonist, Atosiban, is currently used therapeutically for the treatment of PTL. We have previously shown that Atosiban fails to inhibit the pro-inflammatory effects of OT in human amnion, and Atosiban alone activates NF-κB and MAPKs thus upregulating downstream pro-labour genes. In contrast to our findings with Atosiban, the presence of the orally active OTR antagonist, Nolasiban, reduced the effect of OT on NF-κB and p38 kinase activation both in myometrial and amnion cells. Consistent with the activation of these inflammatory mediators, OT led to increases in the expression of COX-2 and ...

Amniotic sac - WikipediaAmniotic sac - Wikipedia
The amniotic sac, commonly called the bag of waters, sometimes the membranes, is the sac in which the fetus develops in amniotes. It is a thin but tough transparent pair of membranes that hold a developing embryo (and later fetus) until shortly before birth. The inner of these fetal membranes, the amnion, encloses the amniotic cavity, containing the amniotic fluid and the fetus. The outer membrane, the chorion, contains the amnion and is part of the placenta. On the outer side, the amniotic sac is connected to the yolk sac, the allantois and, via the umbilical cord, to the placenta. Amniocentesis is a medical procedure where fluid from the sac is sampled to be used in prenatal diagnosis of chromosomal abnormalities and fetal infections. The amniotic cavity is the closed sac between the embryo and the amnion, containing the amniotic fluid. The amniotic cavity is formed by the fusion of the parts of the amniotic fold, which first makes its appearance at the cephalic extremity, and subsequently at ...

Research supported by The Eye Cancer Foundation has proved greater efficacy of this new technique in recreating the outer surface of the eye and inner surface of the eyelids. As published in the American Journal of Ophthalmology on November 2018, tumors of the conjunctiva and eyelids were surgically removed, then amniotic membranes from donor human placentas were sewn into the defects to recreate a normal ocular and inner eyelid surface. Thus, amnion can provide a foundational platform for new cells to grow and flourish. In this case series, super thick amniotic membrane grafts (AMGs) were found to facilitate the healing of wounds. How exactly does graft thickness affect the success of treatment? Well, the greater thickness means it is more easily sewn into the affected area, and. also helps the grafts to remain several weeks after placement. Thicker grafts are less likely to tear, rupture, or dissolve during the postoperative period. Most importantly, following treatment with ST-AMG, every ...

In this study we aimed to set up an in vitro culture of the rabbit amnion in order to support in vivo fetal membrane healing capacity following fetoscopy. Fetal membranes were collected from a mid- gestational rabbit, and cultured on collagen support material for 14 days. 34 rabbits at 22 - 23 days gestational age ( GA) underwent fetoscopy. The entry site was randomly allocated to 4 closure technique study groups: group I, human amnion membrane ( n = 23); group II, collagen foil ( n = 16); group III, collagen plug ( n = 19), and group IV, collagen plug with cultured amnion cells ( n = 19). In all groups membrane access sites were additionally sealed with fibrin sealant, and the myometrium was closed with sutures. Fetal survival, amnion membrane integrity, and the presence of amniotic fluid were evaluated at 30 days GA. Cultures showed good survival in the collagen support material. Increased cellularity, survival and proliferations were observed. The amnion at the access site resealed in 58 - ...

Ocular surface is composed of corneal and conjunctival epithelial cells. Normal cornea is essential for normal vision. Defects in renewal and repair of ocular surface as a result of limbal stem cell deficiency are now known to cause varying ocular surface morbidity including persistent photophobia, repeated and persistent surface breakdown and overt conjunctivalisation of the cornea. Restoring ocular health in these eyes has traditionally been frustrating. Ex vivo cultured limbal epithelial stem cells have been used successfully to treat limbal stem cell deficiency. Ex-vivo limbal stem cell allograft transplantation is achieved by harvesting limbal corneal tissue from donor eyes (either matched living relatives or cadaveric donors). The donor stem cells are obtained by excising a small area of the conjunctiva at the limbus and are a minor procedure. The tissue so obtained is then grown in tissue culture and once the cells have multiplied sufficiently, small sheets are transplanted on to the ...

Our purpose was to evaluate the diagnostic value of three-dimensional (3 D) CT surface reconstruction in spinal fractures in comparison with axial and reformatted images. A total of 50 patients with different CT-proven spinal fractures were analysed retrospectively. Based on axial scans and reformatted images, the spinal fractures were classified according to several classifications as Magerl for the thoraco-lumbar and lower cervical spine by one radiologist. Another radiologist performed 3 D CT surface reconstructions with the aim of characterizing the different types of spinal fractures. A third radiologist classified the 3 D CT surface reconstruction according to the Magerl classification. The results of the blinded reading process were compared. It was checked to see in which type and subgroup 3 D surface reconstructions were helpful. Readers one and two obtained the same results in the classification. The 3 D surface reconstruction did not yield any additional diagnostic information concerning type

Approaches providing the positioning of human amniotic membrane (HAM) within the intra-articular space of arthritic TMJs have never been investigated. This contrasts with the increasing amount of evidence suggesting the potential positive effects of HAM on a number of surgical conditions, even included the interpositional arthroplasty for TMJ ankylosis. Thus, the possible usefulness of HAM to restore joint functions in severely damaged TMJs could be hypothesized. Based on these premises, the clinical research question Is human amniotic membrane positioning effective to reduce symptoms and restore jaw function in patients with severe inflammatory-degenerative disorders of the temporomandibular joint? has been addressed by performing a systematic review of the literature ...

Introduction: Human amniotic membrane (AM) is the innermost layer of placenta and is composed of three distinct strata, namely single epithelial layer, a thick basement membrane and avascular stroma. AM has been widely adopted as a biomaterial in tissue engineering and surgical reconstructions, since it promotes wound healing and epithelialization, has low immunogenicity, reduces inflammation and scarring, and was also shown to possess anti-cancer properties (1). We have shown that AM promotes formation of highly differentiated urothelium, in particular when urothelial cells are cultured on AM stromal side (2). Although AM stroma scaffold allows establishment of differentiated urothelium, its orientation probably does not favour AM integration into surrounding tissue, if applied in vivo. Therefore, we established an in vitro AM model which would allow incorporation of fibroblasts into the AM stroma as well as promote urothelial differentiation.. Materials and Methods: Porcine bladder fibroblasts ...

JCI - Interaction between Borrelia burgdorferi and endothelium in vitro.JCI - Interaction between Borrelia burgdorferi and endothelium in vitro.
During the pathogenesis of Lyme disease, Borrelia burgdorferi spreads hematogenously from the site of a tick bite to several tissues throughout the body. The specific mechanism of spirochete emigration is presently unknown. Using cultured human umbilical vein endothelial cells, we found that Borrelia burgdorferi bound to the endothelial cells and to the subendothelial matrix. Low passage isolates adhered 22-30-fold greater than a strain maintained in culture continuously. Spirochete binding to subendothelial matrix was inhibited 48-63% by pretreatment of the matrix with anti-fibronectin antiserum. Spirochete migration across endothelial monolayers cultured on amniotic membrane was increased when the monolayers were damaged by chemical or physical means. Electron microscopic examination of spirochete-endothelial interactions demonstrated the presence of spirochetes in the intercellular junctions between endothelial cells as well as beneath the monolayers. Scanning electron microscopy identified a ...

Gestational sac - WikipediaGestational sac - Wikipedia
The gestational sac is the large cavity of fluid surrounding the embryo. During early embryogenesis it consists of the extra-embryonic coelom, also called the chorionic cavity. The gestational sac is normally contained within the uterus. It is the only available structure that can be used to determine if an intrauterine pregnancy exists until the embryo is identified. On obstetric ultrasound, the gestational sac is a dark (anechoic) space surrounded by a white (hyperechoic) rim. The gestational sac is spherical in shape, and usually located in the upper part of the fundus of the uterus. By approximately 9 weeks of gestational age, the amniotic sac has expanded to occupy the majority of the volume of the gestational sac, eventually expanding to reduce the extraembryonic coelom to a thin layer between the amnion membrane and the mesoderm. By then, the gestational sac is usually simply called the amniotic sac. During embryogenesis, the extraembryonic coelom (or chorionic cavity) that ...

The human tissue inhibitor of metalloproteinases (TIMP) is a glycoprotein with a molecular weight of 28,000. It appears to be ubiquitous in human mesoderm tissues and has previously been shown to be identical to the collagenase inhibitor isolated from human skin fibroblasts. TIMP inhibits type I- and IV-specific collagenases and other neutral metalloen-doproteinases that may be responsible for the degradation of extracellular matrix in tumor cell metastasis. In this work we have utilized recombinant human TIMP (rTIMP) obtained by expression of its cDNA gene (Carmichael et al., Proc. Natl. Acad. Sci. USA, 83: 2407, 1986). The rTIMP is shown to have similar inhibition properties as natural TIMP against human skin fibroblast collagenase. In an in vitro amnion invasion assay system, rTIMP inhibited the invasion of B16-F10 murine melanoma cells through the human amniotic membrane at an identical concentration to that reported previously for natural TIMP. The mechanism by which rTIMP inhibits amniotic ...

Review preclinical studies on placenta-derived cells and amniotic membrane - Cell GenuityReview preclinical studies on placenta-derived cells and amniotic membrane - Cell Genuity
Recent years have seen considerable advances in our knowledge of the biology and properties of stem/progenitor cells isolated from placental tissues. This has encouraged researchers to address the potential effects of these cells in animal models of different diseases, resulting in increasing expectations regarding their possible utility for cell-based therapeutic applications. This rapidly evolving research field is also enriched by studies aimed at expanding the use of the whole amniotic membrane (AM), a well-known surgical material, for pathological conditions other than those tested so far and for which clinical applications already exist. In this review, we provide an update on studies that have been performed with placenta-derived cells and fragments of the entire AM to validate their potential clinical applications in a variety of diseases, in particular those associated with degenerative processes induced by inflammatory and fibrotic mechanisms.

Amniotic fluid, known as the patron saint of the baby, can play a role in alleviating external shocks, stabilizing the temperature in the uterus, inhibiting bacteria and reducing infection, lubricating after breaking water and disinfection of the birth canal. In fact, there is a word amniotic fluid in medicine, which is translated into Chinese as amniotic fluid for short. The origin of amniotic fluid has the meaning of nourishing and Yang, but its implication has the meaning of nurturing, sunshine and growth, but in fact, the most appropriate and scientific explanation is the amniotic fluid. < p > < p > because the fetus is wrapped in the amniotic membrane and grows and develops through the nutrient fluid in the amnion. Therefore, the clear amniotic fluid also represents that the baby can absorb more and better nutrition. < / P > < p > although I always want to have a natural birth, for the sake of the health and safety of the baby, a cesarean section was carried out in advance one ...

A human heteroploid epithelial-like cell line, designated as C-SPT, was recovered from one of several lots of human WI-38 fibroblast-like diploid cells that lacked evidence of Regan isozyme in early passages. In later passages with the growth of C-SPT cells, high activity of Regan type of alkaline phosphatase appeared as judged by l-phenylalanine inhibition, heat stability, and immunoelectrophoresis. The C-SPT cells appeared to be the progeny of an unidentified source contaminant rather than of transformed WI-38 cells. Comparative enzymological and immunological studies with HeLa and WISH cells confirmed the presence of Regan type of alkaline phosphatase as a characteristic of HeLa and established its presence in WISH cells. However, the specific activity of Regan isozyme in WISH cells was only 3 to 6% of that in C-SPT cells. The HeLa cells exhibited 33% of C-SPT level on the initial passage level studied, which after further cell passage declined to 8%. A HeLa clone was isolated showing very ...

The mechanisms responsible for the onset of labor in women are not completely understood. Growing evidence suggests that bacterial products such as endotoxin could stimulate monocytes or macrophages to produce inflammatory cytokines such as IL-1, TNF, IL-6 and IL-8, which in turn stimulate prostaglandin biosynthesis by amnion, chorion and decidua and result in the onset of labor. Amniotic fluid IL-6 could be a sensitive indicator for prospective diagnosis of acute histologic chorioamnionitis, so amniotic fluid IL-6 is considered as an important cytokine. IL-13 and TIMP-3, recently described, have been known to relate to IL-6. IL-13, a novel T-helper cell lymphokin, has been shown to upregulate IL-6 production in keratinocytes, endothelial cells and mesothelial cells, whereas it downregulates IL-6 production in human monocytes. Tissue inhibitor of metalloproteinase-3(TIMP-3), new type distinct from TIMP-1 and TIMP-2, is known to be stimulated by IL-6. In this study , we examined C3H pregnant mice ...

Childbirth - Academic KidsChildbirth - Academic Kids
A typical human childbirth will begin with the onset of contractions of the uterus. The frequency and duration of these contractions varies with the individual. The onset of labour may be sudden or gradual. A gradual onset with slow cervical change towards 3 cm (just over 1 inch) dilation is referred to as the latent phase. A woman is said to be in active labour when contractions have become regular in frequency (3-4 in 10 minutes) and about 60 seconds in duration. The now powerful contractions are accompanied by cervical effacement and dilation greater than 3cm. The labour may begin with a rupture of the amniotic sac, the paired amnion and chorion (breaking of the water). The contractions will accelerate in frequency and strengthen. In the transition phase from 8cm-10cm (3 or 4 inches) of dilation, the contractions often come every two minutes are typically lasting 70 - 90 seconds. Transition is often regarded as the most challenging and intense for the mother. Some mothers say things ...

  • The present report documents that type IV collagen is lost from the rat amnion before the onset of labor. (levelofhealth.com)
  • The relative decline in type IV collagen could be the result of diminished synthesis, accumulation of other proteins in the amnion which alters the relative abundance of type IV collagen, increased degradation, or a combination of these processes. (levelofhealth.com)
  • Since amnion type IV collagen levels are reduced to some extent before the rise in MMP-2 and MMP-9 protein and activity, it is likely that these enzymes are not responsible for this phase of the decline. (levelofhealth.com)
Early amnion1
  • The hypothesis of an intrinsic defect of germ plasma put forward by Streeter to explain the abnormalities observed in 'amniotic bands sequence' (ABS) was not supported by Torpin, who suggested that the bands derived from early amnion rupture, with formation of mesodermal strings and naked chorion, which then constricted or adhered to fetal parts.
