Central Taurus

The central body (centrosome), located in the center of the cell and containing the central vacuole, is an obligatory compartment of the eukaryotic cell.

Functions of the Centrosome The central body consists of two separate disks called zone A and zone B. Zone A is usually larger than zone B, and both disks are connected to the outer cell membrane. The central vacuole is surrounded by numerous microtubules and microfilaments, which play a role in organizing the central vacuole and connecting to all cell organelles. The interior of the central body is zone A, which surrounds zone B. Zone A contains central tubules, central microtubule disks, small or large centrioles, and a variety of other microdevices, most of which have no clearly defined functional purpose. Zone B is located closer to the outer cellular membrane and is surrounded by zone A, leaving a large void in the center of the central body. The inner surface of this zone is filled with fibrillar material. Both discs interact with the cell's cytoskeleton and move it around the cell, providing internal division. With this function, they coordinate the movement of many particles within the cell, such as mitochondria and ribosomes. This is due to the fact that vacuolization of these microorganizations is concentrated predominantly on centrosome disks. In the central body, microviruses, in particular Sindbis, are concentrated before the cell turns, stimulating the formation of new villi. Inside the cell, they play an important role in the formation of future membrane vesicles in which they are later found. Therefore, the presence of a central body is a necessary condition for the formation and functioning of new membrane compartments from which the vesicles responsible for active transport and, thus, cellular movement are formed. Role of the centrosome in cell transformation In some cases, when there is a need to make a new contact between cells belonging to another cell line, newly formed contacts are required to communicate between these cell lines on the basis of a specific bridge. These “cell-to-cell contacts” provide communication between two cells and often occur as a result of the branching process that usually accompanies cell spread across the surface of a monolayer. A very important event preceding the appearance of such contact is the formation of a triple bridge, to which we will devote the next chapter in this section. Triple bridges are an extended structure containing fibrous connective tissue formed by the secretion of macrophages. The boundaries of this triple bridge allow the cell to select an appropriate junction point between two previously unknown cell lineages. The expansion of the tissue associated with the triple bridge then reduces the stiffness of the triple bridge and to stretch between the two cell lines, while the cell lines themselves continue to expand faster than the triple bridge, so that they cross it by their own flexibility. As a result, after the complete cessation of the production of the triple bridge, they maintain mechanical contact that can be transformed into the final intercellular connections, then they become richer and richer in the deposition of axonal conductors.
