-=== Introduction === 
- 
-This model of cell polarity shows the coupling of three model formalisms: 
-  * A cellular Potts model 
-  * A PDE model, solved on the membrane of the cell 
-  * And an external gradient. 
- 
-The cell membrane polarizes in response to the external gradient. Chemotactic cell motility depends on the polarity of the cell and the external gradient.   
- 
-=== Description === 
-This example implements two models of cell polarity: Meinhardt's substrate-depletion model and Edelstein-Keshet's wave-pinning model. The user can switch polarity model by ''Disabling''/''Enabling'' the relevant ''System''. 
- 
-The model defines a one-dimensional reaction-diffusion system (''MembraneProperty'') representing membrane-bound molecules, and is mapped to a cellular Potts model defining a discrete shaped cell. An external gradient, specified in a ''PDE'', provides a signal for the polarization of the cell. In turn, the polarity of the cell influences its ''chemotaxic'' behavior.  
- 
-After a switch in direction of the gradient, the cell re-polarizes in the new direction and starts to move up the gradient, iff the wave pinning model has been selected.
