Polar Fluctuations Lead to Extensile Nematic Behavior in Confluent Tissues

  title={Polar Fluctuations Lead to Extensile Nematic Behavior in Confluent Tissues},
  author={Andrew Killeen and Thibault Bertrand and Chiu Fan Lee},
  journal={arXiv: Soft Condensed Matter},
How can a collection of motile cells, each generating contractile nematic stresses in isolation, become an extensile nematic at the tissue-level? Understanding this seemingly contradictory experimental observation, which occurs irrespective of whether the tissue is in the liquid or solid states, is not only crucial to our understanding of diverse biological processes, but is also of fundamental interest to soft matter and many-body physics. Here, we resolve this cellular to tissue level… 
Flow around topological defects in active nematic films
We study the active flow around isolated defects and the self-propulsion velocity of +1/2 defects in an active nematic film with both viscous dissipation (with viscosity η) and frictional damping Γ
Fluctuation-induced features of topological defects in passive nematics
Topological defects are increasingly being identified in various biological systems, where their characteristic flow fields and stress patterns are associated with continuous active stress generation


Emergence of Active Nematic Behavior in Monolayers of Isotropic Cells.
A minimal model of cellular monolayers based on cell deformation and force transmission at the cell-cell interface that explains the formation of topological defects and captures the flow-field and stress patterns around them is presented.
Perfect nematic order in confined monolayers of spindle-shaped cells.
Experiments performed in cross-shaped patterns show that in the situation of two competing populations, both the number of cells and the degree of alignment impact the final orientation, which prevents the development of infinite domains.
Biomechanical ordering of dense cell populations
A continuum model of collective cell dynamics based on equations for local cell density, velocity, and the tensor order parameter is developed and used to elucidate the mechanism of cell ordering and quantify the relationship between the dynamics of cell proliferation and the spatial structure of the population.
Motility-driven glass and jamming transitions in biological tissues.
A self-propelled Voronoi (SPV) model is studied that simultaneously captures polarized cell motility and multi-body cell-cell interactions in a confluent tissue, where there are no gaps between cells, and precisely captures a jamming transition from a solid-like state to a fluid- like state.
Celebrating Soft Matter's 10th Anniversary: Cell division: a source of active stress in cellular monolayers.
It is shown that the experimentally measured flow field of dividing Madin-Darby Canine Kidney (MDCK) cells is reproduced by the modeling approach and the fingering instabilities induced by cell division are compared to experimental observations on the expansion of MDCK cell cultures.
Low-noise phase of a two-dimensional active nematic system.
This work systematically study the two-dimensional fluctuating ordered phase in a coarse-grained hydrodynamic description involving both the nematic director and the conserved density field, showing that the system always displays only quasi-long-ranged orientational order beyond a crossover scale.
Long-Lived Giant Number Fluctuations in a Swarming Granular Nematic
Working with a fluidized monolayer of macroscopic rods in the nematic liquid crystalline phase, giant number fluctuations consistent with a standard deviation growing linearly with the mean are found, in contrast to any situation where the central limit theorem applies.
Intrinsic Free Energy in Active Nematics
Basing our arguments on the theory of active liquid crystals, we demonstrate both analytically and numerically, that the activity can induce an effective free energy which enhances ordering in
Correlating cell shape and cellular stress in motile confluent tissues
This work provides a unifying framework for existing, seemingly distinct notions of stress in tissues and relates stresses to material properties and shows that the temporal correlation function of shear stresses can be used to define an effective tissue viscosity that diverges at the liquid–solid transition.
Edges impose planar alignment in nematic monolayers by directing cell elongation and enhancing migration.
Light is shed on the importance of edges in imposing nematic order in confluent monolayers and how edges can be used as tools to pattern the long-range organization of cells for tissue engineering applications.
