THE FORMATION OF A SINGLE CENTRE AND REORGANISATION OF THE CYTOSKELLETON IN THE POLYCARYONS

Abstract

It has been shown, that in the polycaryons life cycle, the stage-by-stage formation of a single cellular centre, analogous to the cellular centre of the single-nuclear cells in structure, takes place. In the life cycle of the polycaryon, a single centersome is twice active as the microtubes organisation centre (MTOC) and once as the intermediate filaments organisation centre (IFOC). The beginning of the formation of the single cellular centre has been timed to the first activation of a single centersome as MTOS. At the same time, the approximation of the nuclei and the aggregation of the secondary lysosomes in the polycaryons take place. The disturbance of the microfilaments integrity with cytochalasine B brings to the delay of formation of the single cellular sentre; the inactivation of a single centersome as the intermediate filament organisation sentre; to the displacement of the nuclei and intermediate filaments to the polycaryons peripheryAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
