Abstract
Cell mechanics controls a wide range of important cell functions, including cell migration, differentiation, polarization, and division. The viscoelastic properties of the nucleus and cytoplasm can be probed with high spatial and temporal resolutions using the method of particle tracking microrheology. In this method, the spontaneous displacements of submicron beads are tracked and rheological parameters, including viscoelastic moduli and creep compliance, are computed from the mean squared displacements. Particle tracking microrheology has revealed changes in cell mechanics associated to wound healing, embryonic development, and human diseases, including laminopathies and cancer.
