Abstract
Cell division requires a dynamic reorganization of cytoskeletal and nuclear components. One essential step is the separation of centrosomes, which allows the assembly of a microtubule-based mitotic spindle. This has to be spatially and temporally coordinated with other events such as adhesion complex disengagement, assembly of an actin-rich cell cortex and nuclear envelope breakdown (NEB), to ensure chromosome segregation fidelity. Previous methodologies often focused on a single event and failed to provide an integrated view of the process. In this chapter, we describe a method to study mitosis with high resolution, by analyzing the dynamic interplay between centrosomes, nucleus, and cell membrane, using a combination of live-cell imaging and micromanipulation with custom-designed computational tools.
