Biologically active materials such as bacterial biofilms and eukaryotic cells thrive in confined micro-spaces. Here, we show through numerical simulations that confinement can serve as a mechanical guidance to achieve distinct modes of collective invasion when combined with growth dynamics and the intrinsic activity of biological materials. We assess the dynamics of the growing interface and classify these collective modes of invasion based on the activity of the constituent particles of the…

Biofilm Growth Under Elastic Confinement
TLDR
A poroelastic framework is utilised to derive the radial growth rate of the biofilm; it reveals an additional self-similar expansion regime, governed by the stiffness of the matrix, leading to a finite maximum radius, consistent with the experimental observations of growing Bacillus subtilis biofilms confined by PDMS.
Tissue flow through pores: a computational study
TLDR
Compared to an unconstricted channel, the presence of a bottleneck perturbs the formation of regular hexagonal arrangements in the epithelial sheet and leads to pile-ups and backflow of cells near the entrance to the constriction, which also affects the overall invasion speed.
Concentration banding instability of a sheared bacterial suspension
Abstract We demonstrate a novel shear-induced mechanism for growth of concentration fluctuations in a bacterial suspension. Using a linear stability analysis, a homogeneous bacterial suspension,
Active nematics with anisotropic friction: the decisive role of the flow aligning parameter.
TLDR
These findings emphasise the role of the flow aligning parameter in the dynamics of active nematics and show that the synergistic effects of friction anisotropy and flow tumbling can lead to the emergence of bound pairs of topological defects that align at an angle to the easy flow direction and navigate together throughout the domain.
Topological Point Defects of Liquid Crystals in Quasi-Two-Dimensional Geometries
We review the interactions and dynamics of topological defects in liquid crystals (LCs) in quasi-two-dimensional (2D) geometries. Such spatial restrictions can be realized in thin freely suspended
Recent advances of injectable hydrogels for drug delivery and tissue engineering applications
Abstract Injectable hydrogel is a kind of in situ gelling system but has its specificity on the process procedure, which requires a better control of gelation kinetics. Hydrogels with injectability
Propagation of active nematic-isotropic interfaces on substrates.
TLDR
A hydrodynamic multiphase model is used to investigate the propagation of interfaces of active nematics on substrates and finds an activity dependent threshold, above which the turbulent active nematic forms isolated islands that shrink until the system becomes isotropic and below which theActive nematic expands, with a well defined propagating interface.

Emergence of three-dimensional order and structure in growing biofilms
TLDR
Single-cell tracking of up to 10,000 bacteria reveals the structure and dynamics of 3D biofilms—providing evidence to suggest that both local ordering and global biofilm architecture emerge from mechanical interactions.
Biomechanical ordering of dense cell populations
TLDR
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.
Recent advances in studying single bacteria and biofilm mechanics.
TLDR
This review presents recent advances on the understanding of how bacterial mechanical properties determine biofilm tri-dimensional growth and eventual dispersion and attempts to draw a parallel between these properties and the mechanical properties of other well-studied hydrogels and living systems.
Active nematics
TLDR
The authors review the subfield of active nematics and provide a comparison between theoretical findings and the corresponding experimental realisations and focus primarily on microtubule–kinesin mixtures and the hydrodynamic theories that describe their properties.
Confined Flow: Consequences and Implications for Bacteria and Biofilms.
TLDR
Understanding of how flow near surfaces and within channels and pores alters physical processes that control how bacteria disperse, attach to surfaces, and form biofilms will inform the development and deployment of technologies for drug delivery, water treatment, and antifouling coatings and guide the structuring of bacterial consortia for production of chemicals and pharmaceuticals.
Biological Tissues as Active Nematic Liquid Crystals.
TLDR
The main focus is on the use of this framework in the systematic study of predominantly 2D tissue architectures and dynamics in vitro and how the nematic state is important in tissue behavior, such as epithelial expansion, tissue homeostasis, and the atherosclerosis disease state.
Celebrating Soft Matter's 10th Anniversary: Cell division: a source of active stress in cellular monolayers.
TLDR
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.
Bacterial biofilms: from the Natural environment to infectious diseases
TLDR
It is evident that biofilm formation is an ancient and integral component of the prokaryotic life cycle, and is a key factor for survival in diverse environments.
Emergence of Active Nematic Behavior in Monolayers of Isotropic Cells.
TLDR
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.
Dynamics of anisotropic tissue growth
We study the mechanics of tissue growth via cell division and cell death (apoptosis). The rearrangements of cells can on large scales and times be captured by a continuum theory which describes the
