Syncytium
Definition:
(n.) Tissue in which the cell or partition walls are wholly wanting and the cell bodies fused together, so that the tissue consists of a continuous mass of protoplasm in which nuclei are imbedded, as in ordinary striped muscle.
(n.) The ectoderm of a sponge.
Example Sentences:
(1) The possibility of unequivocally detecting syncytium-inducing strains after only a few days of coculture will make this detection routine and rapid.
(2) A putative mechanism by which p56lck affects the syncytium formation is also discussed.
(3) The lymph matrix consists of a cytoplasmic syncytium within which nuclei, mitochondria and various sized granules and membranous structures occur.
(4) Another part of bicarbonate is transported as ion using an anion exchange system, which exists in both the multivillous and the basal membranes of the syncytium.
(5) Placental HGF was expressed strongly in the villous syncytium, extravillous trophoblast, and amnionic epithelium, and, to a lesser degree in endothelial cells and villous mesenchyme.
(6) The maturation of feline syncytium-forming virus (FSFV), a member of the foamy virus sub-family (Spumavirinae), has been studied by electron microscopy of thin sections of infected feline embryo (FEA) cells.
(7) These changes are followed from one side, by an atrophy of the blood vessels and connective tissue cells, and from the other, there increases the number of decidua giant cells, as well as of syncytium and cytotrophoblast.
(8) Electron miscroscopy shows that the pooled components of the fused monocytes are not randomly dispersed in the syncytium, but are highly reorganized into a functioning unit.
(9) Syncytium formation between HUT-78 cells persistently infected with human immunodeficiency virus type 1 (HIV-1) and uninfected CD4-bearing MOLT-4 or CEM cells results in a rapid destruction of the MOLT-4 or CEM cells.
(10) When the envelope expression level was increased 10-fold or more, several additional mutants (APG, GAG, GSG, GQG, GVG, and GPF) also induced syncytium formation.
(11) As invasion continued trophoblastic villi, consisting of cores of cytotrophoblast covered by a continuous layer of syncytium, penetrated deeper into the endometrium.
(12) Pregnancy-associated protease inhibitors were detected in the syncytium of the villi of all histological types and also in the fetal and maternal blood.
(13) The chromosome abnormalities were so severe that it is highly improbable that mitosis led to successful nuclear multiplication within a given syncytium.
(14) The murine monoclonal antibody (MAb) 5A8, which is reactive with domain 2 of CD4, blocks human immunodeficiency virus type 1 (HIV-1) infection and syncytium formation of CD4+ cells (L. C. Burkly, D. Olson, R. Shapiro, G. Winkler, J. J. Rosa, D. W. Thomas, C. Williams, and P. Chisholm, J.
(15) Tromantadine most likely inhibits a cellular process that is required for syncytium formation, such as glycoprotein processing, which occurs after the synthesis of the fusion protein but before its expression on the cell surface.
(16) Either sulfatide- or cholesterol sulfate-containing liposomes effectively prevented syncytium formation induced by BIV-infected cells, but the inhibitory effect of sulfatide alone on syncytium formation was low.
(17) Four monkeys that had been immunized with the env product produced antibody against HTLV-I gp68 and gp46, and their sera were found to cause strong inhibition of syncytium formation of a cat fibroblast cell line induced by HTLV-I.
