Spindle Micro-Fluctuations of Length Reveal its Dynamics Over Cell Division
Abstract
3074-Pos. The mitotic spindle ensures correct segregation of sister chromatids and correct partitioning in daughter cells. It comprises dynamical microtubules (alternating polymerizing and depolymerizing), a variety of molecular motors and their regulators. Although spindle structure is well known, the link to its functions remains elusive, calling for including the dynamics of its components and their interactions. This question was mostly investigated by in silico or in vitro approaches. But a detailed characterizing of spindle mechanics, in physiological conditions, is missing
