Overview of mean-field model parameters.

γSS(S)	stem cell division rate
γA(S)	stem cell differentiation rate into CP (type A) cells
Δ	loss rate of CP cells
Γ	birth rate of post-mitotic (type B) cells
γ(B)	basal layer exit rate of post-mitotic cells
c0	cell areal density (=1 cell per unit area)
σ	effective cell mobility
χ	ratio of elastic (fast) diffusion to mixing (slow) diffusion
J	strength of stem cell adhesion
α	surface tension of stem cell adhesion
rSS(S), rΔ, rΓ	‘bare’ division rates (linear coefficients of rate density dependencies)
