Effect of adhesion geometry and rigidity on cellular force distributions [PDF]
Phys Rev Lett 103, 048101 (2009), 2009 The behaviour and fate of tissue cells is controlled by the rigidity and geometry of their adhesive environment, possibly through forces localized to sites of adhesion. We introduce a mechanical model that predicts cellular force distributions for cells adhering to adhesive patterns with different geometries and rigidities.

Biomimetic emulsions reveal the effect of homeostatic pressure on cell-cell adhesion [PDF]
, 2012 Cell-cell contacts in tissues are continuously subject to mechanical forces due to homeostatic pressure and active cytoskeleton dynamics. While much is known about the molecular pathways of adhesion, the role of mechanics is less well understood. To isolate the role of pressure we present a dense packing of functionalized emulsion droplets in which ...

Recent advance in surface modification for regulating cell adhesion and behaviors
Nanotechnology Reviews, 2020 Cell adhesion is a basic requirement for anchorage-dependent cells to survive on the matrix. It is the first step in a series of cell activities, such as cell diffusion, migration, proliferation, and differentiation.

Some fundamentals of adhesion in synthetic adhesives [PDF]
Biofouling, 2016 Various adhesion mechanisms that have been understood in the field of synthetic adhesives are described and these are linked with situations relevant to fouling issues. The review mainly deals with mechanical aspects of adhesion phenomena, with an emphasis on the role of the elasticity of the bodies, called substrata, attached by adhesive.

Langmuir, 2006 The adhesion of microcapsules to an attractive contact potential is studied theoretically. The axisymmetric shape equations are solved numerically. Beyond a universal threshold strength of the potential, the contact radius increases like a square root of

Scientific Reports, 2022 The roughness and wettability of surfaces exploited by free-ranging geckos can be highly variable and attachment to these substrates is context dependent (e.g., presence or absence of surface water). Although previous studies focus on the effect of these

Probing mechanical interaction of immune receptors and cytoskeleton by membrane nanotube extraction
Scientific Reports, 2023 The role of force application in immune cell recognition is now well established, the force being transmitted between the actin cytoskeleton to the anchoring ligands through receptors such as integrins. In this chain, the mechanics of the cytoskeleton to

EpCAM promotes endosomal modulation of the cortical RhoA zone for epithelial organization
Nature Communications, 2021 The organization and force-generating property of actomyosin dictate the plasticity and behaviour of cells but the spatio-temporal regulation of this network is unclear.

Controlling T cells spreading, mechanics and activation by micropatterning
Scientific Reports, 2021 We designed a strategy, based on a careful examination of the activation capabilities of proteins and antibodies used as substrates for adhering T cells, coupled to protein microstamping to control at the same time the position, shape, spreading ...
