Bacterial chromosomal loci move subdiffusively through a viscoelastic cytoplasm.
Tracking of fluorescently labeled chromosomal loci in live bacterial cells reveals a robust scaling of the mean square displacement (MSD) as τ(0.39). We propose that the observed motion arises from relaxation of the Rouse modes of the DNA polymer within the viscoelastic environment of the cytoplasm. The time-averaged and ensemble-averaged MSD of chromosomal loci exhibit ergodicity, and the velo...
متن کاملDroplets move over viscoelastic substrates by surfing a ridge
Liquid drops on soft solids generate strong deformations below the contact line, resulting from a balance of capillary and elastic forces. The movement of these drops may cause strong, potentially singular dissipation in the soft solid. Here we show that a drop on a soft substrate moves by surfing a ridge: the initially flat solid surface is deformed into a sharp ridge whose orientation angle d...
متن کاملHitchhiking Through the Cytoplasm
We propose an alternative mechanism for intracellular cargo transport which results from motor-induced longitudinal fluctuations of cytoskeletal microtubules (MTs). The longitudinal fluctuations combined with transient cargo binding to the MTs lead to long-range transport even for cargos and vesicles having no molecular motors on them. The proposed transport mechanism, which we call “hitchhikin...
متن کاملMeasuring cell viscoelastic properties using a force-spectrometer: influence of protein-cytoplasm interactions.
Cell adhesive and rheological properties play a very important role in cell transmigration through the endothelial barrier, in particular in the case of inflammation (leukocytes) or cancer metastasis (cancer cells). In order to characterize cell viscoelastic properties, we have designed a force spectrometer (AFM) which can stretch cells thereby allowing measurement of their rheological properti...
متن کاملDiffusion of a fluid through a viscoelastic solid
Abstract. This paper is concerned with the diffusion of a fluid through a viscoelastic solid undergoing large deformations. Using ideas from the classical theory of mixtures and a thermodynamic framework based on the notion of maximization of the rate of entropy production, the constitutive relations for a mixture of a viscoelastic solid and a fluid (specifically Newtonian fluid) are derived. B...
