syncytium-forming virus
members of the family Retroviridae, genus Spumavirus. The best known of these viruses are found in cats and cattle. It should be noted, however, that viruses of several families, including herpesviruses, paramyxoviruses, coronaviruses and retroviruses, produce syncytia.

The function of these plasmodesmata was studied afterwards, which showed that during the establishment of the syncytium, plasmodesmata are important connections to the phloem for the symplastic movement of nutrients (Hofmann and Grundler, 2007).
The basal membrane of capillaries and syncytium is thickened, and sclerotic.
nigra (type I) is destined to be engulfed and digested by the embryo and the second type of yolk cell will form the yolk syncytium where blastomeric division takes place.
Normally the multinucleated cells and membrane-bound particles of syncytium undergo controlled apoptosis.
The medial layer of the CS, having no smooth muscle, instead contains at least a thin layer of the striated myocardial fibers orientated along its long axis, forming a delicate network of true muscular syncytium.
In PI 437654, an increase in deposition of cell wall materials in cells surrounding the forming syncytium precedes the collapse of the syncytium, resulting in an incompatibility response (Mahalingam and Skorupska, 1996).
One hour later, the migrating inner blastomeres have reached the blastoderm, while the nuclei of their outer sister cells have entered the yolk cell, contributing to the yolk syncytium (Fig.
Histological abnormalities described in parasitized placenta show pathological changes that could reduce the area of syncytium exposed to maternal blood and, thus, impair materno-foetal exchanges (7).

These fingers extend from a single thin cell, called the syncytiotrophoblast or the placental syncytium, which contains multiple nuclei.
The virus targets the bronchoalveolar epithelium and infects contiguous, uninfected cells by fusing infected cells with uninfected cells (ie, syncytium formation).
Completion of meiosis in the egg does not generally depend upon fertilization, mitosis activating factors reside in the central part of the egg, and all early mitotic divisions occur in a syncytium with no cytological barriers separating the nuclei.
