Modeling the mechanobioelectricity of cell clusters

Area of Science:

• Multiphysics modeling
• Cellular biomechanics
• Bioelectricity

Background:

• Cell clusters exhibit complex mechanical and electrical behaviors.
• Understanding the interplay between bioelectricity and poromechanics is crucial for developmental biology.

Purpose of the Study:

• To develop a continuum finite strain theory for coupled bioelectricity and poromechanics in cell clusters.
• To model water and ion transport mechanisms within and across cell membranes and intercellular spaces.

Main Methods:

• Compressible hyperelasticity for cytoskeletal mechanics.
• Modeling of water fluxes (osmosis, electro-osmosis, pressure) and ion fluxes (electro-diffusion, convection).
• Finite element analysis of a 1D axisymmetric model with permeable/impermeable boundaries.

Main Results:

• Spatiotemporal evolution of ion and water concentrations.
• Prediction of membrane potential and cellular deformation.
• Demonstration of coupled biophysical processes in a cell cluster.

Conclusions:

• The proposed model provides a framework for investigating developmental mechanobioelectricity.
• It can be extended to include genetic, biochemical, and growth dynamics.
• This tool aids in understanding complex cellular behaviors during development.
