In the blood the antigen is found on the surface of NEUTROPHILS; EOSINOPHILS; and MONOCYTES. In addition, CD15 antigen is a stage-specific embryonic antigen.Teratoma: A true neoplasm composed of a number of different types of tissue, none of which is native to the area in which it occurs. It is composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm. They are classified histologically as mature (benign) or immature (malignant). (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1642)Globosides: Glycosphingolipids containing N-acetylglucosamine (paragloboside) or N-acetylgalactosamine (globoside). Globoside is the P antigen on erythrocytes and paragloboside is an intermediate in the biosynthesis of erythrocyte blood group ABH and P 1 glycosphingolipid antigens. The accumulation of globoside in tissue, due to a defect in hexosaminidases A and B, is the cause of Sandhoff disease.Glycosphingolipids: Lipids containing at least one monosaccharide residue and either a sphingoid or a ceramide (CERAMIDES). They are subdivided into NEUTRAL GLYCOSPHINGOLIPIDS comprising monoglycosyl- and oligoglycosylsphingoids and monoglycosyl- and oligoglycosylceramides; and ACIDIC GLYCOSPHINGOLIPIDS which comprises sialosylglycosylsphingolipids (GANGLIOSIDES); SULFOGLYCOSPHINGOLIPIDS (formerly known as sulfatides), glycuronoglycosphingolipids, and phospho- and phosphonoglycosphingolipids.

This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.Antigens, Protozoan: Any part or derivative of any protozoan that elicits immunity; malaria (Plasmodium) and trypanosome antigens are presently the most frequently encountered.Antigens, Polyomavirus Transforming: Polyomavirus antigens which cause infection and cellular transformation. The large T antigen is necessary for the initiation of viral DNA synthesis, repression of transcription of the early region and is responsible in conjunction with the middle T antigen for the transformation of primary cells. Small T antigen is necessary for the completion of the productive infection cycle.HLA Antigens: Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans.

It is also called nucleotide sequence.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Antigens, Fungal: Substances of fungal origin that have antigenic activity.Antigens, CD: Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.Antigens, Helminth: Any part or derivative of a helminth that elicits an immune reaction.

Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Mice, Inbred C57BLMice, Inbred BALB CGene Expression Profiling: The determination of the pattern of genes expressed at the level of GENETIC TRANSCRIPTION, under specific circumstances or in a specific cell.HLA-DR Antigens: A subclass of HLA-D antigens that consist of alpha and beta chains.

Both chains can be polymorphic although there is more structural variation in the beta chains. The class II antigens in humans are called HLA-D ANTIGENS and are coded by a gene on chromosome 6. In mice, two genes named IA and IE on chromosome 17 code for the H-2 antigens. The antigens are found on B-lymphocytes, macrophages, epidermal cells, and sperm and are thought to mediate the competence of and cellular cooperation in the immune response. The term IA antigens used to refer only to the proteins encoded by the IA genes in the mouse, but is now used as a generic term for any class II histocompatibility antigen.Mice, Transgenic: Laboratory mice that have been produced from a genetically manipulated EGG or EMBRYO, MAMMALIAN.Cloning, Molecular: The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.Prostate-Specific Antigen: A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.O Antigens: The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)Receptors, Antigen, B-Cell: IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES.

An overexpression of TIMP-2 has been shown to inhibit invasive and metastatic activity of tumor cells and decrease tumor growth in vivo.Gene Expression Regulation: Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control (induction or repression) of gene action at the level of transcription or translation.HLA-A2 Antigen: A specific HLA-A surface antigen subtype. Members of this subtype contain alpha chains that are encoded by the HLA-A*02 allele family.Antigens, CD8: Differentiation antigens found on thymocytes and on cytotoxic and suppressor T-lymphocytes. CD8 antigens are members of the immunoglobulin supergene family and are associative recognition elements in MHC (Major Histocompatibility Complex) Class I-restricted interactions.T-Lymphocytes: Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.Reverse Transcriptase Polymerase Chain Reaction: A variation of the PCR technique in which cDNA is made from RNA via reverse transcription. The resultant cDNA is then amplified using standard PCR protocols.Transcription Factors: Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.Gene Expression Regulation, Plant: Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in plants.Enzyme-Linked Immunosorbent Assay: An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.Drosophila Proteins: Proteins that originate from insect species belonging to the genus DROSOPHILA.

Several subspecificities of the surface antigen are known. These were formerly called the Australia antigen.Antigens, CD3: Complex of at least five membrane-bound polypeptides in mature T-lymphocytes that are non-covalently associated with one another and with the T-cell receptor (RECEPTORS, ANTIGEN, T-CELL). The CD3 complex includes the gamma, delta, epsilon, zeta, and eta chains (subunits). When antigen binds to the T-cell receptor, the CD3 complex transduces the activating signals to the cytoplasm of the T-cell. The CD3 gamma and delta chains (subunits) are separate from and not related to the gamma/delta chains of the T-cell receptor (RECEPTORS, ANTIGEN, T-CELL, GAMMA-DELTA).Larva: Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.Cross Reactions: Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.HLA-A Antigens: Polymorphic class I human histocompatibility (HLA) surface antigens present on almost all nucleated cells. At least 20 antigens have been identified which are encoded by the A locus of multiple alleles on chromosome 6. They serve as targets for T-cell cytolytic responses and are involved with acceptance or rejection of tissue/organ grafts.Multigene Family: 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)Polymerase Chain Reaction: In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.Phenotype: The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.Matrix Metalloproteinase 2: A secreted endopeptidase homologous with INTERSTITIAL COLLAGENASE, but which possesses an additional fibronectin-like domain.Sequence Alignment: The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.Mutation: Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.In Situ Hybridization: A technique that localizes specific nucleic acid sequences within intact chromosomes, eukaryotic cells, or bacterial cells through the use of specific nucleic acid-labeled probes.Histocompatibility Antigens Class I: Membrane glycoproteins consisting of an alpha subunit and a BETA 2-MICROGLOBULIN beta subunit. In humans, highly polymorphic genes on CHROMOSOME 6 encode the alpha subunits of class I antigens and play an important role in determining the serological specificity of the surface antigen. Class I antigens are found on most nucleated cells and are generally detected by their reactivity with alloantisera. These antigens are recognized during GRAFT REJECTION and restrict cell-mediated lysis of virus-infected cells.Sequence Homology, Amino Acid: The degree of similarity between sequences of amino acids. This information is useful for the analyzing genetic relatedness of proteins and species.Signal Transduction: The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain).

Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.Lymphocyte Activation: Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.HLA-D Antigens: Human immune-response or Class II antigens found mainly, but not exclusively, on B-lymphocytes and produced from genes of the HLA-D locus. They are extremely polymorphic families of glycopeptides, each consisting of two chains, alpha and beta. This group of antigens includes the -DR, -DQ and -DP designations, of which HLA-DR is most studied; some of these glycoproteins are associated with certain diseases, possibly of immune etiology.Antibody Specificity: The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.Receptors, Antigen: Molecules on the surface of B- and T-lymphocytes that recognize and combine with specific antigens.Antigens, CD45: High-molecular weight glycoproteins uniquely expressed on the surface of LEUKOCYTES and their hemopoietic progenitors. They contain a cytoplasmic protein tyrosine phosphatase activity which plays a role in intracellular signaling from the CELL SURFACE RECEPTORS. The CD45 antigens occur as multiple isoforms that result from alternative mRNA splicing and differential usage of three exons.Hepatitis B Antigens: Antigens of the virion of the HEPATITIS B VIRUS or the Dane particle, its surface (HEPATITIS B SURFACE ANTIGENS), core (HEPATITIS B CORE ANTIGENS), and other associated antigens, including the HEPATITIS B E ANTIGENS.Gene Transfer Techniques: The introduction of functional (usually cloned) GENES into cells. A variety of techniques and naturally occurring processes are used for the gene transfer such as cell hybridization, LIPOSOMES or microcell-mediated gene transfer, ELECTROPORATION, chromosome-mediated gene transfer, TRANSFECTION, and GENETIC TRANSDUCTION. Gene transfer may result in genetically transformed cells and individual organisms.Kidney: Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.Alternative Splicing: A process whereby multiple RNA transcripts are generated from a single gene. Alternative splicing involves the splicing together of other possible sets of EXONS during the processing of some, but not all, transcripts of the gene. Thus a particular exon may be connected to any one of several alternative exons to form a mature RNA. The alternative forms of mature MESSENGER RNA produce PROTEIN ISOFORMS in which one part of the isoforms is common while the other parts are different.Antigens, CD4: 55-kDa antigens found on HELPER-INDUCER T-LYMPHOCYTES and on a variety of other immune cell types. CD4 antigens are members of the immunoglobulin supergene family and are implicated as associative recognition elements in MAJOR HISTOCOMPATIBILITY COMPLEX class II-restricted immune responses. On T-lymphocytes they define the helper/inducer subset. CD4 antigens also serve as INTERLEUKIN-15 receptors and bind to the HIV receptors, binding directly to the HIV ENVELOPE PROTEIN GP120.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Antigen-Antibody Reactions: The processes triggered by interactions of ANTIBODIES with their ANTIGENS.Antigens, CD1: Glycoproteins expressed on cortical thymocytes and on some dendritic cells and B-cells. Their structure is similar to that of MHC Class I and their function has been postulated as similar also. CD1 antigens are highly specific markers for human LANGERHANS CELLS.Fluorescent Antibody Technique: Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.Mice, Knockout: Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.Antibodies, Bacterial: Immunoglobulins produced in a response to BACTERIAL ANTIGENS.Immune Sera: Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen.Transcription, Genetic: The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION.Antibody Formation: The production of ANTIBODIES by proliferating and differentiated B-LYMPHOCYTES under stimulation by ANTIGENS.HLA-B Antigens: Class I human histocompatibility (HLA) surface antigens encoded by more than 30 detectable alleles on locus B of the HLA complex, the most polymorphic of all the HLA specificities. Several of these antigens (e.g., HLA-B27, -B7, -B8) are strongly associated with predisposition to rheumatoid and other autoimmune disorders. Like other class I HLA determinants, they are involved in the cellular immune reactivity of cytolytic T lymphocytes.Exons: The parts of a transcript of a split GENE remaining after the INTRONS are removed. They are spliced together to become a MESSENGER RNA or other functional RNA.Antigens, Differentiation: Antigens expressed primarily on the membranes of living cells during sequential stages of maturation and differentiation. As immunologic markers they have high organ and tissue specificity and are useful as probes in studies of normal cell development as well as neoplastic transformation.Immunization: Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).Oligonucleotide Array Sequence Analysis: Hybridization of a nucleic acid sample to a very large set of OLIGONUCLEOTIDE PROBES, which have been attached individually in columns and rows to a solid support, to determine a BASE SEQUENCE, or to detect variations in a gene sequence, GENE EXPRESSION, or for GENE MAPPING.B-Lymphocytes: Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.Sequence Analysis, DNA: A multistage process that includes cloning, physical mapping, subcloning, determination of the DNA SEQUENCE, and information analysis.MART-1 Antigen: A melanosome-specific protein that plays a role in the expression, stability, trafficking, and processing of GP100 MELANOMA ANTIGEN, which is critical to the formation of Stage II MELANOSOMES.

Lipid rafts enriched in monosialylGb5Cer carrying the stage-specific embryonic antigen-4 epitope are involved in development of...
Lipid rafts enriched in glycosphingolipids (GSLs), cholesterol and signaling molecules play an essential role not only for signal transduction started by ligand binding, but for intracellular events such as organization of actin, intracellular traffic and cell polarity, but their functions in cleavage division of preimplantation embryos are not well known. Here we show that monosialylGb5Cer (MSGb5Cer)-enriched raft domains are involved in development during the cleavage stage of mouse preimplantation embryos. MSGb5Cer preferentially localizes at the interfaces between blastomeres in mouse preimplantation embryos. Live-imaging analysis revealed that MSGb5Cer localizes in cleavage furrows during cytokinesis, and that by accumulating at the interfaces, it thickens them. Depletion of cholesterol from the cell membrane with methyl-beta-cyclodextrin (MbCD) reduced the expression of MSGb5Cer and stopped cleavage. Extensive accumulation of MSGb5Cer at the interfaces by cross-linking with ...

Changes in expression of fibroblast growth factor receptors during development of the mouse retinofugal pathway. - Physiology,...
Retinal axons undergo several changes in organization as they pass through the region of the optic chiasm and optic tract. We used immunocytochemistry to examine the possible involvement of fibroblast growth factor receptors (FGFR) in these changes in retinal axon growth. In the retina, at all ages examined, prominent staining for FGFR was seen in the optic fiber layer and at the optic disk. At embryonic day 15 (E15), FGFR immunoreactivity was also detected in the ganglion cell layer, as defined by immunoreactivity for islet-1. At later developmental stages (E16 to postnatal day 0), FGFR were found in the optic fiber layer and the inner plexiform layer. In the ventral diencephalon, immunostaining for FGFR was first detected at E13 in a group of cells posterior to the chiasm. These cells appeared to match the neurons that are immunopositive for the stage-specific embryonic ...
Glycoengineering of host mimicking type-2 LacNAc polymersand Lewis X antigens on bacterial cell surfaces
Bacterial carbohydrate structures play a central role in mediating a variety of host-pathogen interactions. Glycans can either elicit protective immune response or lead to escape of immune surveillance by mimicking host structures. Lipopolysaccharide (LPS), a major component on the surface of Gram-negative bacteria, is composed of a lipid A-core and the O-antigen polysaccharide. Pathogens like Neisseria meningitidis expose a lipooligosaccharide (LOS), which outermost glycans mimick mammalian epitopes to avoid immune recognition. Lewis X (Gal beta 1-4(Fuc alpha 1-3)GlcNAc) antigens of Helicobacter pylori or of the helminth Schistosoma mansoni modulate the immune response by interacting with receptors on human dendritic cells. In a glycoengineering approach we generate human carbohydrate structures on the surface of recombinant Gram-negative bacteria, such as Escherichia coli and Salmonella enterica sv. Typhimurium that lack O-antigen. A ubiquitous building block in mammalian ...
From stem cells to male germ cells: Experimental approaches for the in vitro generation of mouse and human spermatogonial stem...
Currently different in vitro experimental approaches make use of the unique potential of pluripotent cells in order to produce functional sperm aiming at the establishment of new treatment opportunities for male infertility. The establishment of proliferating human spermatogonial stem cell (SSC) lines and their in vitro differentiation into haploid male germ cells represents one of these approaches and was tried to succeed in the presented thesis. The isolation of human SSCs from testicular biopsies from infertile men was performed using the Magnetic Activated Cell Separation technique and succeeded several times in the enrichment of putative SSCs, characterized by their grape-like structures characteristically for SSCs and a positive SSC marker staining. Despite of numerous attempts and testing of different culture conditions, a stable and proliferating human SSC cell line could not be established. Because other studies also revealed great difficulties in the establishment ...
CD15 (3-fucosyl-N-acetyl-lactosamine) is a cluster of differentiation antigen - an immunologically significant molecule. CD15 is a carbohydrate adhesion molecule that can be expressed on glycoproteins, glycolipids and proteoglycans. CD15 mediates phagocytosis and chemotaxis, found on neutrophils; expressed in patients with Hodgkin disease, some B-cell chronic lymphocytic leukemias, acute lymphoblastic leukemias, and most acute nonlymphocytic leukemias. It is also called Lewis x and SSEA-1 (stage-specific embryonic antigen 1) and represents a marker for murine pluripotent stem cells, in which it plays an important role in adhesion and migration of the cells in the preimplantation embryo. It is synthezised by FUT4 (fucosyltransferase 4) and FUT9. CD15 is present on almost all Reed-Sternberg cells, including their rare mononuclear variants, and, as such, can be used in immunohistochemistry to ...

Human Corneal Limbal Stromal Cells provide a source of Mesenchymal Stem Cells | IOVS | ARVO Journals
Purpose : Mesenchymal stem cell (MSC)-based therapy is under investigation as a treatment strategy to promote tissue repair and to modulate the immune system in immune mediated disorders. MSCs have been isolated from many tissues most commonly from the bone marrow or fat. Given the cumbersome procedures for harvesting bone marrow (BM), and to a lesser extent fat, there is a need to look for other tissues for MSC isolation. The International Society for Cellular Therapy (ISCT) has established three criteria for characterizing human MSCs: adherence to plastic, differentiation potential, and the presence or absence of certain cell surface markers. We evaluated whether or not corneal limbal stromal cells (CLSC) met ISCT criteria by comparing them to BM-MSCs. Methods : BM-MSCs were isolated from healthy human bone marrow donors. CLSC were isolated from human corneal limbus from research cadaver corneas (generously provided by Eversight). Both cell types were ...

Helicobacter pylori Lipopolysaccharide Binds to CD14 and Stimulates Release of Interleukin-8, Epithelial Neutrophil-Activating...
Our studies demonstrate that H. pylori LPS stimulates the release of both neutrophil-activating, C-X-C chemokines (IL-8 and ENA-78) and the monocyte-activating C-C chemokine MCP-1 from human monocytes. These chemokines are potent leukocyte chemoattractants and may play an important role in regulating inflammatory cell infiltration of H. pylori-infected gastric mucosa (7, 11, 14, 15,20, 21, 23, 27, 37, 40, 48). We found that H. pyloriLPS is less potent than Salmonella lipid A in inducing monocyte chemokine production. This finding agrees with previous studies showing low potency for H. pylori LPS in the induction of a wide variety of host inflammatory responses (9, 18,19, 34, 36, 38, 39, 42). However, when the actions of H. pylori LPS were specifically inhibited by using either an LPS antagonist or CD14 receptor blockade, the monocyte-activating potential of H. pylori water extract was almost completely abolished. These findings suggest that H. pylori LPS may be the primary ...

We tested this hypothesis using sialyl Lewis X-dependent B16 melanoma lung targeting and its inhibition with selectin ligand mimicry peptide, IELLQAR. In E/P-selectin doubly deficient mutant mice, sialyl Lewis X-expressing B16 melanoma cells colonized the lung, and IELLQAR inhibited this colonization. However, tumors grown in E/P-selectin-deficient mice were significantly smaller than those grown in wild-type mice. These results indicate that the IELLQAR peptide receptor expressed in the lung ...
An enzymatic ruler modulates lewis antigen glycosylation of helicobacter pylori lps during persistent infection
Helicobacter pylori persistently colonizes about half the human population and contributes to the development of peptic ulcer disease and gastric cancer. This organism has evolved means to structurally alter its surface characteristics to evade innate and adaptive immune responses. H. pylori produces LIPS O-antigen units that can be posttranslationally fucosylated to generate Lewis antigens, structures also found on human epithelial cells. We demonstrate an extensive diversity of Lewis x and Lewis y expression in LPS O-antigen units, occurring over time and in different regions of the human stomach. Lewis expression patterns were correlated with the on/off status of the three fucosyltransferases (FucT), FutA, FutB, and FutC, which are regulated via slipped-strand mispairing in intragenic polyC tract regions of the corresponding genes. The alpha 1,3-FucT, FutA and FutB, each contain a C-terminal heptad repeat region, consisting of a variable number of DD/NLRV/INY tandem ...
Transcripts of α-(1,3)-fucosyltransferases in human epithelial cancer and leukemia cell lines were analyzed by Northern blotting and reverse transcriptase mediated-polymerase chain reaction using specific probes and primers which can discriminate between the transcripts derived from the four α-(1,3)-fucosyltransferase genes Fuc-TIII, IV, V, and VI. Flow cytometric analysis of the sialyl Lex and sialyl Lea antigens was also performed on the same cell lines. The sialy Lex antigen was expressed on 14 of 15 epithelial cancer cell lines, and the sialyl Lea antigen was detected on 8 of them. The message of Fuc-TIII was detected in most of the epithelial cancer cell lines (14 of 15), which correlated with the surface expression of these carbohydrate determinants. In addition, the messages of Fuc-TIV and Fuc-TVI were detected in most epithelial cancer cell lines, while the message of Fuc-TV was undetectable in most of them. On the other hand, all leukemia cell lines ...

The α-(1,2) fucosyltransferases (Fut1 and Fut2) and α-(1,3) fucosyltransferases (Fut4, Fut9) are responsible for the synthesis of Lewis X (LeX) and Lewis Y (LeY) conjugated to glycoproteins. We recently reported that these fucosyltransferases were differentially expressed in the reproductive tract of male mouse. Here, we studied the effect of androgen on fucosyltransferase expression through the use of mouse castration models. We found that Fut1 mRNA and Fut4 mRNA were upregulated, while Fut2 mRNA and Fut9 mRNA were downregulated by androgen in the caput epididymis. However, in the vas deferens and prostate, only Fut4 mRNA and Fut2 mRNA were respectively upregulated following exposure to androgen. In the seminal vesicle, all fucosyltransferases, with the exception of Fut9, were upregulated. We identified the androgen receptor binding sites (ARBSs) of Fut2, Fut4 and Fut9 in the caput epididymis. Luciferase assay for these ARBSs is able to provide an indication as to why Fut4 and Fut9 are differently
OP0127 In Vitro Chondrogenesis and in VIVO Repair of Osteochondral Defect with Human Induced Pluripotent Stem Cells | Annals of...
Results Mesodermal markers increased in EB while undifferentiated ES markers disappeared. After 21 days of chondrogenic culture in micromass pellets, GAG analysis showed that proteoglycan production was significantly greater in chondrogenic pellets than in undifferentiated hiPSCs and EBs. Safranin-O staining demonstrated that the cells in chondrogenic pellets took on the appearance of immature chondrocytes and secreted extracellular matrix. The chondrogenic marker gene and protein expression increased after 21days of pellet culture. The chondrogenic pellets derived from hiPS cells have very low expression of hypertrophic or osteogenic markers.. Also, hiPS cells underwent good chondrogenic differentiation in PLGA scaffold or alginate gel as well. When hiPS cells in either pellet state or in alginate hydrogel were implanted in the osteochondral defects created on the patellar groove of immunosuppressed rats, the defects implanted with ...

"Dopaminergic neurons derived from human induced pluripotent stem cells" by Jingli Cai, Ming Yang et al.
Cell replacement therapy could be an important treatment strategy for Parkinsons disease (PD), which is caused by the degeneration of dopamine neurons in the midbrain (mDA). The success of this approach greatly relies on the discovery of an abundant source of cells capable of mDAergic function in the brain. With the paucity of available human fetal tissue, efforts have increasingly focused on renewable stem cells. Human induced pluripotent stem (hiPS) cells offer great promise in this regard. If hiPS cells can be differentiated into authentic mDA neuron, hiPS could provide a potential autologous source of transplant tissue when generated from PD patients, a clear advantage over human embryonic stem (hES) cells. Here, we report that mDA neurons can be derived from a commercially available hiPS cell line, IMR90 clone 4, using a modified hES differentiation protocol established in our lab. These ...
Amines, aminooxy (also known as oxylamine), hydrazide, azide, alkyne, BCN, and tyramide reactive dyes, as well as dye free acids, are generally stable in aqueous solution when stored at -20°C for 6-12 months or longer, as long as no compounds are present that may react with the dyes functional group. See the product information sheets for specific reactive dyes more information.. Coelenterazines and D-luciferin. Coelenterazines are stable in solid form when stored as recommended; they are not stable in aqueous solution. Concentrated coelenterazine stock solutions (typically 1-100 mg/mL) should be prepared in ethanol or methanol; do not use DMSO or DMF to dissolve coelenterazines, because these solvents will oxidize the compounds. Ethanol or methanol stocks of coelenterazine can be stored at -20°C or below for six months or longer; alcohol stocks may evaporate during storage, so use tightly sealing screw cap vials and wrap the vials with Parafilm for long term storage. ...

Dynamics associated with spontaneous differentiation of ovarian stem cells in vitro | Journal of Ovarian Research | Full Text
Recent studies suggest that ovarian germ line stem cells replenish oocyte-pool in adult stage, and challenge the central doctrine of fixed germ cell pool in mammalian reproductive biology. Two distinct populations of spherical stem cells with high nucleo-cytoplasmic ratio have been recently identified in the adult mammalian ovary surface epithelium (OSE) including nuclear OCT-4A positive very small embryonic-like (VSELs) and cytoplasmic OCT-4 expressing ovarian germ stem cells (OGSCs). Three weeks culture of scraped OSE cells results in spontaneous differentiation of the stem cells into oocyte-like, parthenote-like, embryoid body-like structures and also embryonic stem cell-like colonies whereas epithelial cells attach and transform into a bed of mesenchymal cells. Present study was undertaken, to further characterize ovarian stem ...
Sialyl Lewis X-i antigen has been used as a tool for the clinical assessment of lung cancers, especially lung adenocarcinoma. However, the carbohydrate antigens including sialyl Lewis X-i antigen are also increased in some patients with non-malignant lung diseases such as IPF without coexistent malignancy.8-12 There is as yet no test to make a specific diagnosis in patients with raised levels of the antigen. When increased serum levels of the antigen are found in patients with IPF without a suspicious mass on the chest CT scan, further invasive and costly tests are often considered to rule out adenocarcinoma originating from other organs. If the core proteins of the antigen in patients with lung adenocarcinoma are not the same as those in patients with IPF, it is expected that the pattern of expression would differ on Western blotting analysis. In order to establish the specific test for a differential diagnosis we evaluated ...

Chronic Helicobacter pylori infection is recognized as a cause of gastric cancer. H. pylori adhesion to gastric cells is mediated by bacterial adhesins such as sialic acid-binding adhesin (SabA), which binds the carbohydrate structure sialyl-Lewis x. Sialyl-Lewis x expression in the gastric epithelium is induced during persistent H. pylori infection, suggesting that H. pylori modulates host cell glycosylation patterns for enhanced adhesion. Here, we evaluate changes in the glycosylation-related gene expression profile of a human gastric carcinoma cell line following H. pylori infection. We observed that H. pylori significantly altered expression of 168 of the 1,031 human genes tested by microarray, and the extent of these alterations was associated with the pathogenicity of the H. pylori strain. A highly pathogenic strain altered expression of several genes involved in glycan biosynthesis, in particular that encoding β3 GlcNAc T5 (β3GnT5), a GlcNAc transferase essential for the biosynthesis ...

Human iPS cells cultured with the DEF-CS system are typically 98% Oct-4 positive, as determined by flow cytometry. They also express common pluripotency markers, including the transcription factors Oct-4 and NANOG and the surface markers SSEA-4, TRA-1-60, and TRA-1-81. The cells do not express the differentiation marker SSEA-1. Cells grown in the DEF-CS system have been shown to differentiate in vitro and in vivo into all three germ layers.. ...
Isolation and characterization of a Sca-1+/CD31-progenitor cell lineage derived from mouse heart tissue | BMC Biotechnology |...
In this article, we successfully isolate Sca-1+ cells from postnatal mice hearts with the MACS system, using a microbead-labeled anti-Sca-1 antibody. The isolated Sca-1+ cells express the stemness markers Nanog and TERT, the cardiac mesoderm markers ISL-1, TBX5, and the cardiac specific transcription factors GATA4, Nkx2.5, and MEF2C. They can be propagated in vitro for a long time without any significant changes in marker expression. Moreover, the isolated Sca-1+ cells and their long-term descendants exhibit multipotent differentiation to cardiac cell lineages, including smooth muscle, endothelial cells and cardiomyocytes. So, the Sca-1+ cells we isolated from mouse heart tissue should be identified as CPCs.. Isolation of a cardiac progenitor cell (CPC) population from the heart is challenging, particularly because of a lack of specific surface markers. ...
TY - JOUR. T1 - The antitumor monoclonal antibody MOv2 recognizes the Lewis A hapten. AU - Leoni, F.. AU - Magnani, J. L.. AU - Miotti, S.. AU - Canevari, S.. AU - Pasquali, M.. AU - Sonnino, S.. AU - Colnaghi, M. I.. PY - 1988. Y1 - 1988. N2 - Monoclonal antibody MOv2, produced against ovarian carcinoma, was previously found to bind a carbohydrate epitope (CAMOv2) present on mucins, glycoproteins and a neutral glycolipid. In this paper, the structure of the carbohydrate epitope is determined by immunological reactivity with purified glycolipids and oligosaccharides. Using solid-phase radioimmunoassay and immunostaining of thin layer chromatograms, MOv2 binds strongly to Le(a)-active pentasaccharide ceramide. A smaller neutral glycolipid also weakly binds MOv2. Fifty percent inhibition of binding to Le(a)-active pentasaccharide ceramide is achieved with approximately 8 μM concentration of lacto-N-fucopentaose II (LNF II). Lacto-N-tetraose (LNT) also partially inhibits at about 103 times higher ...

Clinical characteristics and biopsy accuracy in suspected cases of Sjögren's syndrome referred to labial salivary gland biopsy ...
Labial salivary gland biopsy (LSGB) is the most important diagnostic tool for the diagnosis of Sjögrens syndrome (SS), but its diagnostic value is rarely studied. This study assessed the sensibility and specificity of LSGB, and the clinical profiles of patients who were referred for biopsy. Retrospective analysis of the histopathological reports from LSGB and medical report data from patients who underwent LSGB between 2008 and 2011 was conducted. About 290 biopsies were performed and 74 were excluded due to insufficient clinical data. Of the 216 patients, 0.46% was carrier of hepatitis C virus, 30.1% had primary SS (pSS), and 8.8% had secondary SS (sSS). Of the samples, 94.3% presented dryness symptoms, 51.6% experienced dryness only, 42.7% had systemic manifestations, and 66.9% presented low unstimulated salivary flow and/or Schirmers test. LSGB was necessary in 67.6% to confirm the presence of SS based on the American-European Consensus Group 2002 criteria (AECG). Based ...
CD137 enhances monocyte-ICAM-1 interactions in an E-selectin-dependent manner under flow conditions | [email protected]
Expression of CD137, a member of the tumor necrosis factor receptor family, is inducible on vascular endothelial cells by proinflammatory stimuli. Its ligand is expressed as a transmembrane protein on the surface of monocytes, and transmits activating signals into monocytes (reverse signaling) inducing monocyte migration. These findings led to the hypothesis that CD137 expression on activated endothelial cells facilitates recruitment of monocytes into inflammatory tissues including atherosclerotic lesions. Data from this study demonstrate that CD137 expression is inducible on endothelial cells by TNF stimulation. Recombinant CD137 protein and CD137 expressed on activated endothelial cells enhance ICAM-1-mediated adhesion of monocytes under defined flow conditions in vitro. CD137 seems not to play a role in tethering of monocytes since this activity is completely E-selectin-dependent. In addition, LFA-1 affinity and ...
E-selectin is an inducible cell adhesion molecule which mediates rolling of neutrophils as well as adhesion of carcinoma cells to endothelium. Inhibition of selectin-mediated interaction is a possible means for controlling inflammation induced diseases and metastatic spread. The purpose of these studies is to identify peptide forms mimicking Lewis X (LeX), sialyl-Lewis X (SA-LeX), sialyl-Lea (SA-Lea), and Lewis Y (LeY) carbohydrate structures to disrupt lectin-ligand interactions and evaluate their properties to block adenocarcinoma cell adhesion to endothelial cells and tumor metastasis in vitro and in vivo. We used recombinant peptide library to identify novel ligands for E-selectin. We have identified five dodeca peptides mimicking SA-Lea carbohydrate, which is one of the E-selectin ligands, via means of random peptide library screening using SA-Lea-specific monoclonal antibody (MAb) NS 19-9. Peptides with the highest binding affinity for ...

Differentiation in murine erythroleukemic cells is arrested at the proerythroblast stage. A small fraction of the population, however, undergoes spontaneous differentiation. This spontaneous differentiation was examined at the individual cell level in relation to cell multiplication, commitment, and maturation. The results indicate that murine erythroleukemic cells destined to undergo spontaneous differentiation first undergo commitment, an irreversible process characterized by cells becoming (a) capable of producing hemoglobin coupled with (b) a loss of their ability to undergo more than six subsequent cell divisions. Commitment is followed by a maturation process which includes the accumulation of erythroid specific markers, e.g., hemoglobin. With respect to commitment, spontaneous differentiation resembles the differentiation produced by most inducers but differs from that evoked by hemin. Serum hemin may ...

3871 Sialyl Lewis x (sLex) antigen is a carbohydrate antigen that is considered not only a marker for cancer but also implicated functionally in the malignant behaviour of cancer cells. Overexpression of sLex is associated with enhanced progression and metastases of many types of cancer including those of the mammary gland. Canine malignant mammary tumours can invade and give rise to metastases via either lymphatic or blood vessels.. E-Cadherin is specifically involved in epithelial cell-to-cell adhesion. In cancer, E-Cadherin underexpression is one of the alterations that characterizes the invasive phenotype and is considered a potent invasion/tumour suppressor gene. Partial or complete loss of E-Cadherin expression correlates with poor prognosis in canine malignant mammary cancer.. The aim of this study was to analyse the sLex expression in canine malignant mammary tumours and to evaluate if the presence of sLex correlates with the expression of E-Cadherin ...

Cells that were aligned via their DNA centroid (see 1.) were rotated based on either the DNA or their cell boundary contours depending on their specific cell cycle category. For cells in interphase and prophase, the alignment contour was based on the two-dimensional cell membrane contour of the center slice of the z-stack of the cell. For cells in metaphase and anaphase, the alignment contour was based on the two-dimensional maximum intensity projection of the z-stack corresponding to the DNA. For cells in early prometaphase, the alignment contour was generated using one of the two techniques just described depending on the eccentricity of the largest connected component of the DNA. For instance, if that value were below 0.55 the cell would be aligned similar to cells in interphase and prophase; however, if the eccentricity exceeded 0.55, indicating a preferential direction for DNA, the cell ...

2001 Lex was talking on his cell phone and didnt see the baling wire in the road until it was almost too late. He swerved to the side and found himself heading straight for a tall boy in flannel standing on the side of the bridge. "Ahh!" Lex cried out in surprise and alarm. The boy turned, apparently hearing the sports car heading right for him. His eyes widened in fear and he, too, opened his mouth to shout something. Lex didnt think. He just acted. Hed been part of Dumbledores Army and hed fought in the Battle for Hogwarts during his last year there. The wand was in his hand without any conscious decision to draw it from its arm holster. "Wingardium Leviosa!" he cast, launching the boy up into the air as the car hurtled through the space he had so very recently occupied. He heard no scrapping against the roof, so Lex assumed the boy had been thrown clear. He didnt really have much time to process that, though, because the river came up to met him and when it did, Lexs head slammed ...

One of the main benefits of FUT over FUE is that large numbers of follicular units can be transplanted in one session. The greatest number of follicular units transferred during an FUE treatment is about 2,000. On the other hand, an FUT may involve the transfer of 4,000 follicular units. The FUT method also allows for "super sessions", where up to 5,000 follicular units are transferred in one appointment. For patients who need to transplant a large quantity of follicles, these super sessions provide a great convenience, and are often the most economical option. FUT is also the recommended form of treatment for patients who cannot commit to multiple surgery dates. ...
