This model is based on the "Activator Model" in figure 4 and equations (5) through (8) of the following reference:

The SBML Level 2 Version 1 model consists of the following components:

(28 April 2010) Updated notebook compatible with Mathematica Version 7, xlr8r, and Cellzilla2D (6.4 MB Zip, expands to 33.4 MB). For more information on xlr8r and Cellzilla2D click here.
CellzillaML file (XML file: right click to save file  it will not display properly in a web browser. Also requires CelleratorML file, below.) This files contains the geometric information as an XML file and can be used, along with the CelleratorML file, by Cellzilla to reproduce the model in its entirety (for more information on CelleratorML/CellzillaML click here). This information is also contained in the three TSV files listed below so you don't need an xml decoder to retrieve the information.
CelleratorML file (XML file: right click to save file, it will not display properly in browser).
The following CSV files can be used to regenerate the template if you want to run the model in a different simulator. The files vertices.tsv, edges.tsv, and cells.tsv are equivalent to a Voronoi tessletation of centers given in centers.tsv (except along the L1 layers where the cells are truncated to give proper volume rather than extend to infinity).
(3 May 2011) Updated Notebook compatible with Mathematica Version 8, Cellzilla2D, and Cambium v.09 generation. For SBML generation see Mathematica Version 7 Notebook above.
Cambium Model File (see Cambium Project Site for more information on Cambium)
(18 May 2011) Single Cell SBML file or Mathematica8 nb for activator models. These represent the internal reactions within a single cell. Diffusion is not represented in this file. (Use "save link as" option to download files)
