GFtbox Growth factor naming conventions
Prefix
id_ | identity factors (non-diffusible). Identity factors can be labelled as on the A or B side (ida_, idb_) |
s_ | signalling factors (diffuse not including polariser) |
v_ | visualising labels (e.g. theta, bend, kpar, other labels) |
f_ | finite element manipulation (e.g. seams, making holes) |
Suffix
_p | promotor: how much the expression of the factor is being promoted in the model |
_l | level of morphogen, i.e. *_p times *_a. This gets updated at the end of the interaction function and might change according to growth or mutation, see *_a. |
_i | index into the main data structure morphogen field, m.morphogen. |
_a | activity: by default it is 1 and if the factor is mutated or silenced then it is 0. However, it can be in the range [0,...,1]. |
Standard morphogens
Specifying growth
kapar_p,kapar_a,kapar_l | specify growth on the 'A' side parallel to the polariser and in the plane of the tissue |
kbpar_p,kbpar_a,kbpar_l | specify growth on the 'B' side parallel to the polariser and in the plane of the tissue |
kaper_p,kaper_a,kaper_l | specify growth on the 'A' side perpendicular to the polariser and in the plane of the tissue |
kbper_p,kbper_a,kbper_l | specify growth on the 'B' side perpendicular to the polariser and in the plane of the tissue |
knor_p,knor_a,knor_l] | specify growth normal to the plane of the tissue (i.e. thickness) |
Controlling growth
P | Polariser level. |
strainret_p,strainret_a,strainret_l | a number between 0 (no strain retention, default) and 1 (full strain retention). |
kbpar_p,kbpar_a,kbpar_l | a number between 0 (no overall inhibition of growth, default) and 1 (fully inhibited) |
