Spatial distribution of bacteria and extracellular polymeric substances impacts nanoparticle penetration in biofilms

This study investigates how biofilm structure affects nanoparticle penetration using experimental and simulation methods in Salmonella biofilms.

Permissive aggregative group formation favors coexistence in yeast

This study shows that permissive kin recognition in yeast leads to coexistence between cooperators and defectors under varying environmental conditions.

Activity-induced fluidization of arrested coalescence in fusion of cellular aggregates

This study investigates how active cell motility and cortical tension influence spheroid fusion dynamics, showing that cell growth increases coalescence during fusion.

Intercellular adhesion stiffness moderates cell decoupling on stiff substrates

This paper develops a computational model of cell pairs on patterned substrates to study how intercellular adhesion stiffness influences cell decoupling on stiff substrates.

Compaction dynamics during progenitor cell self-assembly reveal granular mechanics

The paper studies self-assembly dynamics of human progenitor cells in agarose micro-wells, finding that aggregates behave as granular piles with density relaxation following a stretched exponential.

The role of actin protrusion dynamics in cell migration through a degradable viscoelastic extracellular matrix: Insights from a computational model

This paper develops a computational model to study how actin protrusion dynamics influence 3D cell migration through a degradable viscoelastic extracellular matrix, revealing key factors affecting migration efficiency and speed.

The effect of cortical elasticity and active tension on cell adhesion mechanics

The paper models cell-cell separation mechanics using a numerical simulation of an elastic shell with active tension and non-specific adhesion, estimating mechanical parameters consistent with experimental data.
