Cellular Potts Model

Introduction Human induced pluripotent stem cells (hiPSCs) can be grown in cell culture where they self-organize spatial patterns. Libby et al. have employed inducible CRISPR interference-driven genetic perturbations to modulate mechanical cell properties like cell-cell adhesion and cortical tension.

Introduction The formation and maintenance of three germ layers in colonies of human embryonic stem cells (ESCs) is sensitive to the geometry of the colony. In vitro experiments with micropatterns controlling colony shape have previously addressed the underlying spatio-temporal patterning in Warmflash et al.

Introduction Collective motion of human breast cancer cells of the cell line MDA-MB-231 was studied by Lee et al. for individual crawling cells, cell doublets, cell quadruplets and for confluent populations on a two-dimensional substrate.

Cells' consumption of cytokine concentration Introduction This example serves to demonstrate the implementation of cells consuming a substrate field, e.g. cytokine. Please also see the built-in docu at MorpheuML/Global/Field and Global/System/DiffEqn.

Introduction The mass-conserving secretion and uptake of (signaling) molecules by cells can in Morpheus be achieved with Mappers and scaling fluxes by cell.volume. The intracellular amount of signal may trigger a change in a state variable that could downstream change cell behaviors.

Membrane pattern allows anisotropic release of substance from cell Introduction This example serves to demonstrate a multiscale model of a cell secreting a substance/molecule and propelling away from the secreted substance.

Example demonstrating how adhesion energies affect cell shape and the cell-cell contact region Introduction We simulate two CPM cells of the same type to demonstrate how adhesion energies affect cell shape and the cell-cell contact region.

Two-parameter plane showing all possible regimes of behavior for a single CPM cell Introduction The idea is based on figure 3 in the referenced paper. Description But here, we use two dimensionless parameters:

Unbiased and biased random walkers Introduction We can simulate the swimming motion of a cell, such as a bacterium, by interspersing short periods of directed motion with random turns or random scrambling of the cell’s velocity.

Time sequence showing the changing shape of a CPM cell Introduction Not all cell shapes are circular. In this example, a single cell undergoes a whole series of deformations resulting in the development of irregular cell shapes.
