Glazier-Graner Model of cell sorting Introduction This model shows the original cellular Potts model (a.k.a. Glazier-Graner model) of cell sorting based on the Steinberg’s differential adhesion hypothesis. Figure 1.

How is the right islet size established during zebrafish pancreas development? Introduction Beta cells in the developing pancreas of zebrafish divide rapidly between 5 and 30 days post fertilization (dpf) and additional beta cells are recruited to the islet.

Hepatocyte–sinusoid alignment (HSA) causes asymmetric shapes in early hepatocellular tumors. Introduction The mammalian liver is subdivided into lobes and further into thousands of hexagonal columns, called lobules, which act in parallel.

Hepatocyte–sinusoid alignment (HSA) supports the coordination of hepatocytes during liver regeneration after damage by carbon tetrachloride. Introduction The regenerative capacity of the mammalian liver did already inspire the fate of Prometheus in Greek Myth but it still poses many questions today that call for spatio-temporal multicellular modeling.

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:

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.

This model also requires the separate file boundary.tiff. Introduction The immune system plays an important role in controlling infections and tumors. Knowledge about the mechanisms through which the immune system accomplishes this can be exploited to develop immunotherapies.

Particles moving left and right (as well as up) to mimic actin filament barbed ends Introduction Particles are moving left and right (as well as up) to mimic actin filament barbed ends as motivated by the referenced paper.
