Simulating Elastogenesis

 

       For my final project, I simulated the self assembly of tropoelastin into an elastin network, following the path from the rough endoplasmic reticulum through the     golgi apparatus, and finally into the extra-cellular matrix.  This process is called elastogenesis. 

 

The process is quite complex, and no doubt involves many complex chemical signaling pathways and specific binding events.  My model is a very crude simplification of the entire process, and should only be considered a Ôproof-of-conceptÕ that processes like this may be simulated with relative ease.

 

I wrote the simulation in processing, and it is based on proximity sensing of molecules which have a specific affinity for one another.

 

For future directions, I think that it would be useful to more accurately capture the physical behavior of the system, including but not limited to specific binding events among the different classes of molecules.

 

The source code for my project may be found here.

 

Videos of the simulations, are below the slides.
