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.
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.
A genus of silkworm MOTHS in the family Bombycidae of the order LEPIDOPTERA. The family contains a single species, Bombyx mori from the Greek for silkworm + mulberry tree (on which it feeds). A native of Asia, it is sometimes reared in this country. It has long been raised for its SILK and after centuries of domestication it probably does not exist in nature. It is used extensively in experimental GENETICS. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p519)
An extra-embryonic membranous sac derived from the YOLK SAC of REPTILES; BIRDS; and MAMMALS. It lies between two other extra-embryonic membranes, the AMNION and the CHORION. The allantois serves to store urinary wastes and mediate exchange of gas and nutrients for the developing embryo.

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.
A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.

Mrj encodes a DnaJ-related co-chaperone that is essential for murine placental development. (1/662)

We have identified a novel gene in a gene trap screen that encodes a protein related to the DnaJ co-chaperone in E. coli. The gene, named Mrj (mammalian relative of DnaJ) was expressed throughout development in both the embryo and placenta. Within the placenta, expression was particularly high in trophoblast giant cells but moderate levels were also observed in trophoblast cells of the chorion at embryonic day 8.5, and later in the labyrinth which arises from the attachment of the chorion to the allantois (a process called chorioallantoic fusion). Insertion of the ROSAbetageo gene trap vector into the Mrj gene created a null allele. Homozygous Mrj mutants died at mid-gestation due to a failure of chorioallantoic fusion at embryonic day 8.5, which precluded formation of the mature placenta. At embryonic day 8.5, the chorion in mutants was morphologically normal and expressed the cell adhesion molecule beta4 integrin that is known to be required for chorioallantoic fusion. However, expression of the chorionic trophoblast-specific transcription factor genes Err2 and Gcm1 was significantly reduced. The mutants showed no abnormal phenotypes in other trophoblast cell types or in the embryo proper. This study indicates a previously unsuspected role for chaperone proteins in placental development and represents the first genetic analysis of DnaJ-related protein function in higher eukaryotes. Based on a survey of EST databases representing different mouse tissues and embryonic stages, there are 40 or more DnaJ-related genes in mammals. In addition to Mrj, at least two of these genes are also expressed in the developing mouse placenta. The specificity of the developmental defect in Mrj mutants suggests that each of these genes may have unique tissue and cellular activities.  (+info)

Canine preprorelaxin: nucleic acid sequence and localization within the canine placenta. (2/662)

Employing uteroplacental tissue at Day 35 of gestation, we determined the nucleic acid sequence of canine preprorelaxin using reverse transcription- and rapid amplification of cDNA ends-polymerase chain reaction. Canine preprorelaxin cDNA consisted of 534 base pairs encoding a protein of 177 amino acids with a signal peptide of 25 amino acids (aa), a B domain of 35 aa, a C domain of 93 aa, and an A domain of 24 aa. The putative receptor binding region in the N'-terminal part of the canine relaxin B domain GRDYVR contained two substitutions from the classical motif (E-->D and L-->Y). Canine preprorelaxin shared highest homology with porcine and equine preprorelaxin. Northern analysis revealed a 1-kilobase transcript present in total RNA of canine uteroplacental tissue but not of kidney tissue. Uteroplacental tissue from two bitches each at Days 30 and 35 of gestation were studied by in situ hybridization to localize relaxin mRNA. Immunohistochemistry for relaxin, cytokeratin, vimentin, and von Willebrand factor was performed on uteroplacental tissue at Day 30 of gestation. The basal cell layer at the core of the chorionic villi was devoid of relaxin mRNA and immunoreactive relaxin or vimentin but was immunopositive for cytokeratin and identified as cytotrophoblast cells. The cell layer surrounding the chorionic villi displayed specific hybridization signals for relaxin mRNA and immunoreactivity for relaxin and cytokeratin but not for vimentin, and was identified as syncytiotrophoblast. Those areas of the chorioallantoic tissue with most intense relaxin immunoreactivity were highly vascularized as demonstrated by immunoreactive von Willebrand factor expressed on vascular endothelium. The uterine glands and nonplacental uterine areas of the canine zonary girdle placenta were devoid of relaxin mRNA and relaxin. We conclude that the syncytiotrophoblast is the source of relaxin in the canine placenta.  (+info)

Formation of mature egg envelope subunit proteins from their precursors (choriogenins) in the fish, Oryzias latipes: loss of partial C-terminal sequences of the choriogenins. (3/662)

The inner layer of egg envelope of the medaka, Oryzias latipes, comprises two major groups of glycoprotein subunits, ZI-1,2 and ZI-3. Their precursor proteins, choriogenin H (Chg H) and choriogenin L (Chg L), respectively, are synthesized in spawning female liver. In the present study, the primary structures of the precursors and the corresponding mature subunits were compared by peptide mapping and amino acid sequencing to find what difference in their molecular structures is relevant to the assembly of the soluble precursors into the insoluble inner layer. The primary structures of the solubilized subunits were mostly identical to those of the respective precursors, but they lacked C-terminal partial sequences that their precursors possessed, namely, ZI-1,2 subunit was shorter than Chg H by 34 amino acid residues and ZI-3 was shorter than Chg L by 27 residues. In addition, a consensus amino acid sequence, Arg-Lys-X-Arg, was found at the putative cleavage sites in the C-terminal region of the precursors. It is conjectured that the truncation of the precursor proteins is prerequisite for formation of mature chorion subunit proteins and their assembly into chorion.  (+info)

CD9 is expressed in extravillous trophoblasts in association with integrin alpha3 and integrin alpha5. (4/662)

The CD9 molecule is a 24-27 kDa cell surface glycoprotein, which may be related to Schwann cell migration and adhesion. In this study, we examined the expression of CD9 in human extravillous trophoblasts, which invade into the endometrium during implantation and placentation. CD9 was detected immunohistochemically on the extravillous trophoblasts in the cell columns of first trimester placentae, but not on villous trophoblasts. In the second and third trimester, CD9 was highly expressed on the extravillous trophoblasts in the basal plate of placentae, and in the chorion laeve in the fetal membrane of term placentae. The molecular mass of CD9 in the chorion laeve was shown to be 27 kDa by Western blotting. The mRNA of CD9 was also detected in the chorion laeve by reverse transcription-polymerase chain reaction (RT-PCR). Proteins were purified from chorion laeve by affinity chromatography with anti-integrin alpha3 and alpha5 monoclonal antibodies and Western blotting, revealed that CD9 was associated with both integrins. These findings indicate that CD9 is a differentiation-related molecule present in the extravillous trophoblasts. Since it is associated with integrin alpha5 which has been proposed to regulate trophoblast invasion, CD9 may be implicated in trophoblast invasion at the feto-maternal interface.  (+info)

Early embryonic lethality in Bmp5;Bmp7 double mutant mice suggests functional redundancy within the 60A subgroup. (5/662)

Members of the BMP family of signaling molecules display a high conservation of structure and function, and multiple BMPs are often coexpressed in a variety of tissues during development. Moreover, distinct BMP ligands are capable of activating common pathways. Here we describe the coexpression of two members of the 60A subfamily of BMPs, Bmp5 and Bmp7, at a number of different sites in the embryo from gastrulation onwards. Previous studies demonstrate that loss of either Bmp5 or Bmp7 has negligible effects on development, suggesting these molecules functionally compensate for each other at early stages of embryonic development. Here we show this is indeed the case. Thus we find that Bmp5;Bmp7 double mutants die at 10.5 dpc and display striking defects primarily affecting the tissues where these factors are coexpressed. The present analysis also uncovers novel roles for BMP signaling during the development of the allantois, heart, branchial arches, somites and forebrain. Bmp5 and Bmp7 do not appear to be involved in establishing pattern in these tissues, but are instead necessary for the proliferation and maintenance of specific cell populations. These findings are discussed with respect to potential mechanisms underlying cooperative signaling by multiple members of the TGF-beta superfamily.  (+info)

A monoclonal antibody against chorion proteins of the sea bass Dicentrarchus labrax (Linnaeus, 1758): studies of chorion precursors and applicability in immunoassays. (6/662)

The monoclonal antibody DLE7 was obtained against 44- to 50-kDa polypeptides solubilized from the vitelline envelope of the Mediterranean sea bass Dicentrarchus labrax. In Western blot analysis of chorion lysates it recognized cross-reactive bands at 44 kDa, 48 kDa, and 110 kDa. Previous affinity blotting with concanavalin-A showed that most of solubilized bands were glycosylated. Enzymatic deglycosylation of chorion proteins followed by Western blot analysis with DLE7 showed that the 48-kDa and 110-kDa antigens were differentially affected by endoglycosidase-F treatment. When DLE7 was employed in immunofluorescence analysis, isolated chorions and ovarian cryosections stained intensely. Positivity was also observed in liver cryosections of spawning females but not in liver of males and nonspawning females. To study the origin and delivery of chorion proteins, DLE7 was used in Western blot analysis of liver homogenates and blood serum of spawning females. Cross-reacting bands were detected in liver (90 kDa) and serum (180 kDa, 50 kDa). DLE7 was also used for the first time to set up an indirect ELISA assay to detect egg antigens in the blood of egg-producing females, raising the possibility of using DLE7 as a female-specific marker of spawning for sea bass.  (+info)

Tissue plasminogen activator and its receptor in the human amnion, chorion, and decidua at preterm and term. (7/662)

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)

Expression of matrix metalloproteinases during murine chorioallantoic placenta maturation. (8/662)

A large body of experimental evidence supports the participation of two groups of extracellular proteases, matrix metalloproteinases (MMPs), and plasminogen activators/plasmin, in tissue remodeling in physiological and pathological invasion. In the late mouse placenta, several tissue remodeling and cell invasion processes take place. Spongiotrophoblast migration into maternal decidua, as well as decidual extracellular matrix remodeling require the coordinated action of extracellular proteolytic enzymes. Via Northern and in situ hybridization, we have analyzed the spatio-temporal expression patterns of members of the MMP family (stromelysin-3, gelatinases A and B), as well as their inhibitors TIMP-1, -2 and -3 in late murine placenta (days 10.5 to 18.5 of gestation). Gelatinase activity in placental extracts was assessed by substrate zymography. Gelatinase A and stromelysin-3 were found to be prominently expressed in decidual tissue; shortly after midpregnancy, the decidual expression patterns of gelatinase A and stromelysin-3 became overlapping with each other, as well as with the expression domain of TIMP-2. On the other hand, gelatinase B transcripts were expressed only by trophoblast giant cells at day 10.5, and were downregulated at later stages. TIMP-1 and TIMP-3 transcripts were detected in decidual periphery at day 10.5, while later the expression was restricted to the endometrial stroma and spongiotrophoblasts, respectively. The areas of stromelysin-3 expression were the same (giant trophoblasts) or adjacent (decidua) to those where urokinase (uPA) transcripts were detected, suggesting a possible cooperation between these proteinases in placental remodeling. We generated mice doubly deficient for stromelysin-3 and uPA, and report here that these mice are viable and fertile. Furthermore, these animals do not manifest obvious placental abnormalities, thereby suggesting the existence of compensatory/redundant mechanisms involving other proteolytic enzymes. Our findings document the participation of MMPs and their inhibitors in the process of late murine placenta maturation, and warrant the characterization of other members of the MMP family, like membrane type-MMPs, in this process.  (+info)

AU - Mahowald, Anthony P.. PY - 1979. Y1 - 1979. N2 - Two bands of putative Drosophila chorion mRNA, E3 and E4, have been shown to hybridize in situ near 7E11 (Spradling and Mahowald, 1979) within a region known to contain a gene, ocelliless, which may be involved in chorion production (Johnson and King, 1974). We have investigated the synthesis of chorion mRNAs and chorion proteins in flies carrying this mutation. A reduction of labeling of both E3 and E4 was observed in stage 12 egg chambers from homozygous ocelliless females. In addition, they produce mature oocytes which contain greatly reduced amounts of several major chorion proteins, including those normally produced in stage 12, c36 and c38. To investigate whether the reduction was due to a direct effect of the mutation, the genes for these proteins were ...
The part of the chorion that is in contact with the decidua capsularis undergoes atrophy, so that by the fourth month scarcely a trace of the villi is left. This part of the chorion becomes smooth, and is named the chorion laeve (from the Latin word levis, meaning smooth). As it takes no share in the formation of the placenta, this is also named the non-placental part of the chorion. As the chorion grows, the chorion laeve comes in contact with the decidua parietalis and these layers fuse. The villi at the embryonic pole, which is in contact with the decidua basalis, increase greatly in size and complexity, and hence this part is named the chorion frondosum. Thus the placenta develops from the chorion frondosum and the decidua basalis. ...

The potential of the developing zebrafish model for toxicology and drug discovery is limited by inefficient approaches to manipulating and chemically exposing zebrafish embryos-namely, manual placement of embryos into 96- or 384-well plates and exposure of embryos while still in the chorion, a barrier of poorly characterized permeability enclosing the developing embryo. We report the automated dechorionation of 1600 embryos at once at 4 h postfertilization (hpf) and placement of the dechorionated embryos into 96-well plates for exposure by 6 hpf. The process removed ≥95% of the embryos from their chorions with 2% embryo mortality by 24 hpf, and 2% of the embryos malformed at 120 hpf. The robotic embryo placement allocated 6-hpf embryos to 94.7% ± 4.2% of the wells in multiple 96-well trials. The rate of embryo mortality was 2.8% (43 of 1536) from robotic handling, the rate of missed wells was 1.2% (18 of 1536), and the frequency of multipicks was ,0.1%.

Enzyme in Fishes:. The chorion contains an enzyme known as chorionase. The chorion also resists digestion by trypsin and pepsin, it possesses pseudo-keratin. The hardening of chorion is due to the enzyme in the perivitelline fluid. Ca++ affects the enzyme rather than chorion itself. Hardening resulted from oxidation of SH to SS groups by means of aldehydes produced by polysaccharide with a glycol groups. Hatching enzyme works best under alkaline condition, pH 7.2-9.6 and temperature of 14-20 °C. Acetyl cholinesterase, the enzyme associated with nervous stimulation of the muscles, has been detected on 10th day after fertilization in Salmo gairdneri eggs. In the eye stage increase in activity is almost coinciding with the development of excitable tissue.

Egg: This egg sometimes appears pink and furry (Plate A), and close examination indicates it has a fine carpet of hairs on the chorion, but other eggs have a clear, glassy chorion (Plate A1). As the embryo develops, the black pigmented expansions on the dorsal finfold thread can be seen through the chorion (B). The egg takes up to 12 days to hatch (24°C). Unfortunately in captive conditions the egg often fails to hatch. Larva: At hatching the impressive larva has well developed eyes and a functional mouth (C). Myomeres are very fine and difficult to count in the larva, but appear to be about 90. Note the additional finger at the tip of each elongate pelvic fin ray, which has been seen in several specimens. C: NH (9 days PC). This egg was uncommon, which is not surprising as regalecids are open ocean fishes, and rarely seen (Heemstra 1986).

TY - JOUR. T1 - Discovery and Characterization of Human Amniochorionic Membrane Microfractures. AU - Richardson, Lauren. AU - Vargas, Gracie. AU - Brown, Tyra. AU - Ochoa, Lorenzo. AU - Sheller-Miller, Samantha. AU - Saade, George. AU - Taylor, Robert N.. AU - Menon, Ramkumar. PY - 2017/12/1. Y1 - 2017/12/1. N2 - This study obtained visual evidence of novel cellular and extracellular matrix-level structural alterations in term and preterm human fetal amniochorionic membranes. Amniochorions were collected from term cesarean (not in labor) or vaginal (labor) deliveries, preterm premature rupture of membranes, and spontaneous preterm birth. To determine the effect of oxidative stress on membranes at term or preterm labor, term not in labor samples in an organ explant culture in vitro were exposed to cigarette smoke extract. Tissues were imaged using multiphoton autofluorescence and second harmonic generation microscopy. Images were analyzed using ImageJ and IMARIS software. Three-dimensional ...
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 ...

Im afraid I have bad news. Chorion can categorically confirm that it does not hold the rights in this series, nor has it been able to identify who exactly does have the rights in this series. The Chorion legal team have invested a huge amount of time into investigating this matter and have been very thorough. We have identified that it was originally produced by the Portman Group under license from Family Film AG and Copyright Promotions (who, in turn, jointly acquired the rights from Darrell Waters Limited). We understand that Family Film AG became part of the Portman Group which is, we understand, now part of the Zenith Group. However, it is impossible for Chorion to identify whether the rights in this series were passed on from Family Film AG to the Portman Group, or from the Portman Group to Zenith. Please remember that this series was produced 30 years ago and that the initial production company no longer exists ...
A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array. (King & Stanfield, A Dictionary of Genetics, 4th ed ...
Rats were observed by using a modified hot plate test before and at different times after formalin injection. Consequently, it calls for mapping the lectin presence in tumours. This supports the usefulness of the PO and TO concepts in describing AH professions and may provide new clues for policy aiming to enhance job satisfaction, retention and career development.

Stages in the Life of a Butterfly Egg Butterfly eggs consist of a hard-ridged outer layer of shell, called the chorion. This is lined with a thin coating of wax, which prevents the egg from drying out before the larva has had time to fully develop. Each egg contains a number of tiny funnel-shaped openings at one end, called micropyles; the purpose of these holes is to allow sperm to enter and fertilize the egg. Butterfly and moth eggs vary greatly in size between species, but they are all either spherical or ovate. Butterfly eggs have a hard outer shell. This protects the larva inside. The shell is called the chorion. Inside, the egg is lined with wax. This keeps the egg from drying out. Not all eggs are the same shape or size. Larva Larvae, or caterpillars, are multi-legged eating machines. They consume plantleaves and spend practically all of their time in search of food. As they mature their skin is shed several times Larvae have three body parts-head, thorax and abdomen. Even though the ...

La vitamine A et ses dérivés actifs (les rétinoïdes) sont des molécules essentielles à la vie et ce dès la période embryonnaire. Molécules de choix dans de nombreuses applications thérapeutiques, notamment dans les domaines de la dermatologie et de lophtalmologie, elles sont le plus couramment utilisées pour leurs propriétés pro-cicatrisantes. Malgré cette utilisation courante en clinique, les mécanismes cellulaires et moléculaires permettant aux rétinoïdes de promouvoir un processus de cicatrisation restent encore mal connus. Afin de mieux appréhender ces mécanismes, mais aussi afin délargir leur utilisation clinique à la rupture prématurée des membranes (RPM), je me suis intéressée aux propriétés pro-cicatrisantes de latRA (lun des dérivés actifs de la vitamine A) sur les membranes fœtales.

Egg: This egg has only been seen once, on 5th July 2009. Due to its size and reticulated shell pattern, it was instantly recognised as being new to this collection. The chorion had a fine hexagonal mesh, with a small vertical projection at each corner (Plate A1). On hatching, the oil globules had coelesced into 1, positioned adjacent to the anus of the larva. Incubation was about 40 hours. Larva: The 3-day larva has lightly pigmented, a partly developed mouth, and abundant yellow pigment in the finfolds (C). The distinguishing feature is the gut which terminates laterally, and not ventrally (C, arrowed). C: 3 days.. The identification is tentative but based on description of macrourid eggs given by Merrett (2006). Efforts to barcode this larva failed; more accurate identification must await further collections. ...

Based in Dublin, Ireland, Brown Bag Films is an animation studio that has been producing award-winning series and short movies since 1994. A couple of years ago, family entertainment company Chorion approached Brown Bag Films to discuss developing an animated series based on Ian Falconer s Olivia books. These beloved children s stories follow the adventures of a mischievous but lovable pig. When they were asked to work on the project, Brown Bag realized they had several challenges. First, they had to convince the books author that they could translate his characters to the small screen. They also had to find a way to produce the series in 3D.
Mr Tickle can never suppress an irresistible urge to tickle everyone within his reach, which, because of his extraordinarily long arms covers a very, very wide range. Hes a mischievous character but kind at heart and hes always willing to use those long arms of his to help people. He is part of the original Mr Men and Little Miss series of books created by Roger Hargreaves in 1971.. In 2011, Sanrio (the creators of Hello Kitty) acquired the licensing rights to the Mr Men and Little Miss characters from Chorion; Costumes With Character produce her exclusively for the license holders Sanrio. Mr Tickle is an oval, orange, inanimate, antron fleece covered character with long wiggly arms, a blue hat and a huge friendly smile.. Please Note: This specific costume is not for sale or hire.

AU - Mangieri, Domenica. AU - Nico, Beatrice. AU - Benagiano, Vincenzo. AU - De Giorgis, Michela. AU - Vacca, Angelo. AU - Ribatti, Domenico. PY - 2008/6. Y1 - 2008/6. N2 - We have attempted a fine characterization of the angiogenic response induced by multiple myeloma endothelial cells (MMEC) by using the chick embryo chorioallantoic membrane (CAM) assay and by reverse transcriptase-polymerase chain reaction (RT-PCR). Results showed that in the CAM assay MMEC induced an angiogenic response comparable to that of a well-known angiogenic cytokine, namely fibroblast growth factor-2 (FGF-2), while RT-PCR demonstrated that the expression of endostatin mRNA detected in MM treated CAM was significantly lower respect to control CAM. These data suggest that angiogenic switch in MM may involve ...

Pericytes are commonly identified by molecular markers, such as desmin. The aim of this study was to analyze the pattern of distribution of desmin in the chick embryo chorioallantoic membrane (CAM) vasculature in normal condition and in response to an angiogenic cytokine, such as fibroblast growth factor-2 (FGF-2) by using conventional immunohistochemistry and confocal laser scanning microscopy. Results indicate that, in normal condition, the desmin-positive pericytes are located ...
The chorioallantoic membrane - also called the chorioallantois or abbreviated to CAM - is a vascular membrane found in eggs of some amniotes, such as birds and reptiles. It is formed by the fusion of the mesodermal layers of two developmental structures: the allantois and the chorion.[1] In mammals, this structure forms the placenta. Three different layers compose the chorioallantoic membrane; these are called the chorionic epithelium, the mesenchyme and the allantoic epithelium. Blood capillaries and sinuses are found between epithelial cells of the chorionic layer, allowing close contact (within 0.2 μm) with air found in pores of the shell membrane of the egg.[2] As a result, the chorioallantoic membrane allows exchange of gases, such as oxygen, to developing embryos.[1] During embryonic development of birds, the chorioallantoic membrane also plays an essential role in bone formation by transporting calcium into the embryo from the eggshell.[1] Chorioallantoic membranes from developing ...
The majority of ovarian cancer patients present with advanced disease and despite aggressive treatment, prognosis remains poor. Significant improvement in ovarian cancer survival will require the development of more effective molecularly targeted therapeutics. Commonly, mouse models are used for the in vivo assessment of potential new therapeutic targets in ovarian cancer. However, animal models are costly and time consuming. Other models, such as the chick embryo chorioallantoic membrane (CAM) assay, are therefore an attractive alternative. CAM assays have been widely used to study angiogenesis and tumor invasion of colorectal, prostate and brain cancers. However, there have been limited studies that have used CAM assays to assess ovarian cancer invasion and metastasis. We have therefore developed a CAM assay protocol to monitor the metastatic properties of ovarian cancer cells (OVCAR-3, SKOV-3 and OV-90) and to study the effect of potential therapeutic molecules in vivo. The results from the CAM assay

Shark (Sinica cetorhinus maximum) cartilage was extracted in 1 mol/L Gu-HCl guanidine. Two purified active proteins with apparent molecular weights of 15.2x103 Da and 8.0×103 Da (designated as Sp15 and Sp8, respectively) were obtained through ultrafiltration and Superdex 75 chromatography. The activities of the samples were studied in terms of their potential inhibition of vascular endothelial cell growth in vitro, of angiogenesis both in rabbit cornea and chick embryo chorioallantoic membrane (CAM) assay models in vivo, and of growth of transplanted S180 sarcoma in mice in vivo. The results showed that Sp15 expressed a typical lysozymatic activity up to 223,000 U/mg and its N-terminus was highly homologous to lysozymes of various mammalian origins. Sp15 exhibited a strong anti-angiogenic activity only in vitro, whereas Sp8 shared this effect both in vitro and in vivo. Both Sp15 and Sp8 provided an effective anti-tumor activity in mice bearing transplanted S180 sarcoma. These results suggest that Sp15
The aims of this work are to study the antitumor effect of the adeno-associated virus on the xenografted tumors of chick embryo chorioallantoic membrane and predict potential genes and biological pathways which are associated with renal cell carcinoma. The adeno-associated virus NT4-TAT-6 × His-VHLbeta was constructed and identified. Then, chick embryos with xenografted tumor were divided into three groups and respectively inoculated with rAAV/NT4-TAT-6 × His-VHLbeta (group A), empty virus (group B), and phosphate-buffered saline (group C, the control subject). Antitumor effect in each group was investigated by means of immunofluorescence observation. Genes interacted with von Hippel-Lindau were screened by Search Tool for the Retrieval of Interacting Genes/Proteins database, while pathway analysis were performed based on Kyoto Encyclopedia of Genes and Genomes. The growth of xenografted tumors inoculated with recombinant adeno-associated virus was slower than the control subjects. The tumor ...
A method for preparing placenta membrane tissue grafts for medical use, includes obtaining a placenta from a subject, cleaning the placenta, separating the chorion tissue from the amniotic membrane, mounting a selected layer of either the chorion tissue or the amniotic membrane onto a drying fixture, dehydrating the selected layer on the drying fixture, and cutting the selected layer into a plurality of tissue grafts. Preferably, the drying fixture includes grooves or raised edges that define the outer contours of each desired tissue graft, after they are cut, and further includes raised or indented logos that emboss the middle area of the tissue grafts during dehydration and that enables an end user to distinguish the top from the bottom side of the graft. The grafts are comprised of single layers of amnion or chorion, multiple layers of amnion or chorion, or multiple layers of a combination of amnion and chorion.

Therapeutic regulation of tissue vascularization has appeared as an attractive approach to treat a number of human diseases. In vivo neovascularization assays that reflect physiological and pathological formation of neovessels are important in this effort. In this report we present an assay where the effects of activators and inhibitors of angiogenesis can be quantitatively and qualitatively measured. A provisional matrix composed of collagen I and fibrin was formed in a plastic cylinder and implanted onto the chick chorioallantoic membrane. A nylon mesh separated the implanted matrix from the underlying tissue to distinguish new from pre-existing vessels. Vascularization of the matrix in response to fibroblast growth factor-2 or platelet-derived growth factor-BB was scored in a double-blinded manner, or vessel density was measured using a semi-automated image analysis procedure. Thalidomide, fumagillin, U0126 and TGFβ inhibited neovessel growth while hydrocortisone exerted a negative and ...

The extra-placental gestational membranes secrete cytokines in response to bacteria and other infectious agents, with potentially adverse consequences for pregnancy. The present study used lipopolysaccharide (LPS) as a prototype endotoxin to investigate the pattern of stimulated cytokine release from the amniotic and choriodecidual sides of full-thickness human gestational membranes in a two-compartment tissue culture system. Gestational membranes were collected from healthy non-laboring caesarean deliveries at term. Full-thickness membranes from each placenta were cut into pieces, mounted on Transwell frames, and placed in culture wells to create a two-compartment culture with the gestational membranes serving as the barrier between compartments. The LPS (100 ng/ml) was added to the amniotic, choriodecidual or both chambers of the culture, and cytokines were assayed in the medium of the amniotic and choriodecidual chambers after 8 h of LPS exposure. Cytokine concentrations were analyzed by two-way

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 ...
Fingerlike projections called villi appear in the chorion. They develop in the following manner. Small areas of the single-layered cellular trophoblast begin to proliferate into cell masses that extend into strands of the syncytial trophoblast. Such a cellular mass is called a primary villus. Toward the end of the second week some of the cell masses change into columns of cells that have a core of extraembryonic mesoblasts. For a short period the core is avascular and is called a secondary villus. During the third week blood vessels differentiate in the extraembryonic mesoblast and connect the villus with the vascular system of the embryo proper. A villus with blood vessels in its core is called a tertiary villus ...

Detailed information on immature stages of Mutillidae is being acquired. However, Clausen (1940) noted that very little information was available regarding the form or habits of immature stages of this family. The egg of Mutilla sp (Williams 1919b) has been described as elongated and curved, with the chorion minutely granulated. It is placed transversely upon the dorsum of a Tiphia larva, between the 1st and 2nd thoracic segments. The point of larval feeding is ventral. Ferton stated that the egg of Stenomutilla argentata var. saundersivora Fer. is attached to the inner wall of the host cocoon. The early larval instars by 1940 had not been described for any species. The mature larva of M. glossinae has 11 pairs of spiracles, located on the 2nd and 3rd thoracic and the first 9 abdominal segments. The mandibles are 4-dentate, while those of M. lunata and M. attenuata are believed to be tridentate. The mature larvae of all species spin a cocoon within the cell, cocoon, or puparium of the host, ...
geth-sem-a-ne (Gethsemanei (for other spellings and accents see Thayer, under the word); probably from the Aramaic gath shemanim, oil press): Mentioned (Mt 26:36; Mk 14:32) as a place (chorion), margin enclosed piece of ground, to which Jesus and the disciples retired after the last supper; in Jn 18:1 it is described as a garden (kepos), while Lk (22:40) simply says place (topos). From Jn 18:1 it is evident that it was across the Kidron, and from Lk 22:39, that it was on the Mount of Olives. Very possibly (Lk 21:37; 22:39) it was a spot where Jesus habitually lodged when visiting Jerusalem. The owner--whom conjecture suggests as Mary the mother of Mark--must have given Jesus and His disciples special right of entry to the spot. Tradition, dating from the 4th century, has fixed on a place some 50 yds. East of the bridge across the Kidron as the site. In this walled-in enclosure once of greater extent, now primly laid out with garden beds, by the owners--the Franciscans--are eight old ...
