Resumen:
Microtubules are long and stiff polymers that form the cytoskeleton of
eucaryotic cells. They perform a series of tasks, such as determining
the cell shape and providing a network of rails along which molecular
motors transport organelles to different parts of the cell. They are
particularly important during the process of cell division, since they
provide the forces by which replicated chromosomes are segregated into
what will be the two daughter cells. Microtubules are formed from a
protein called tubulin and undergo a process called dynamic
instability. In this paper we study, via numerical simulations of some
simplified models, how the interaction between microtubules and the
diffusion of free tubulin affects their spatial organization.
