25. Formation of an organised tissue structure.
The principles of the
previous model are retained (the autostabilisation version) but cell selection
is added in the form of interdependence for survival and proliferation. A cell
must metabolise a minimal quantity of molecules produced by the other cell type.
This selective model involves new parameters — quantities of molecules necessary
for survival and cell division. It induces the formation of an organised tissue struc-
ture as a bilayer of cells.
