Paris\Modelling Variables
From 2007.igem.org
After analysis the design of the different parts and the interaction between them, we define 4 variable of interest and one optional

Number of soma cells (S)
the S (soma cells) are the cells which provide the DAP to the germe cell, so the size of this kind of cells is a very important factor to prevent the system to collapse.
They are issue from the differentiation of the germe cells. So the production of S depends on the number of germe cells, and on the concentration of CRE.
Like all the others cells, S may die, for the moment we think about a linear coefficient to represent the death of the cells.
Number of germe cells (G)
The G (germe cells) are DAP-auxotrophe cells, they can divide or differentiate. More G they are, more DAP is needed, so they depends on S.
G can divide so the shape of the curve of G augmentation is the same as other growth rate evolution.
G can die too, (like for S a linear coefficient), and it can differentiate.
