Cell Migration

Just over 30 years ago, the cellular Potts model (CPM) was introduced to explain experimental observations of spontaneous cell sorting …

This multiscale mechanistic liver lobule model is composed of various interacting cell types, such as hepatocytes, residential Kupffer cells and macrophages. It captures hepatocellular acetaminophen (APAP) metabolism, DNA damage response activation, necrotic cell death, macrophage recruitment and the regulation of hepatocellular senescence and proliferation, with qualitatively different outcomes as a function of the initial APAP concentration in blood plasma.

The migration of zebrafish polster cells is oriented by the migration of follower cells, allowing robust long-range coordination of different cell populations. Introduction Collective cell migration is an important process during biological development and tissue repair.

Guidance-by-followers combined with one of several simple rule sets for integration of signals from multiple neighbors provides a robust mechanism for collective cell migration. Introduction Collective cell migration is an important process during biological development and tissue repair but may turn malignant during tumor invasion.

Introduction Larvae of the nematode Caenorhabditis elegans aggregate into clusters of several hundred moving individuals when starved during their first larval stage (see video below). Avery et al. proposed that starved larvae produce and respond chemotactically to two diffusible chemical signals, a short-range attractant and a longer range repellent.

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.

Morphogenesis, wound healing, and some cancer metastases depend upon the migration of cell collectives that need to be guided to their …

Multiscale simulation of EMT by minimal signaling circuit Introduction We model epithelial-mesenchymal transition (EMT) by first assembling an ODE model for intracellular Yes-associated protein (YAP) signalling and then embedding this single cell model within individual cells in a multiscale simulation.

Simulated sheet morphology for YAP knockdown (KD) and overexpression (OE) Introduction We model epithelial-mesenchymal transition (EMT) by first assembling an ODE model for intracellular Yes-associated protein (YAP) signalling and then embedding this single cell model within individual cells in a multiscale simulation.

Multiple models in epithelial-mesenchymal transitions (EMT) Introduction We model epithelial-mesenchymal transition (EMT) by first assembling an ODE model for intracellular Yes-associated protein (YAP) signalling and then embedding this single cell model within individual cells in a multiscale simulation.
