syncytium A multinucleated cell.
syndrome A group of symptoms characteristic of a particular disease or abnormality.
synergid Two haploid cells on either side of the egg cell at the micropylar end of the embryo sac.
The cells which constitute the wall of the tube proliferate rapidly, lose their cell-boundaries and form a syncytium.
On one hand they act as immunodepressors, and protect the embryo from the immune system of the mother and on the other hand viral fusion proteins cause the formation of the placental syncytium in order to limit the exchange of migratory cells ...
The blastoderm stage of the embryo is a syncytium (thousands of nuclei unconfined by cells) so that, for example, macromolecules like DNA injected into the embryo have easy access to all the nuclei.
Instead it is a syncytium or mass of cytoplasm with numerous nuclei and filled with the highly organized contractile proteins, actin and myosin. Under the light microscope the very regular arrangement of these proteins is striking and characteristic.
