Figure 5.

Tissue stratification and thickness as functions of the death rate of TD cells. (A) Death rate of TD cells (d₂ in unit of per-cell cycle length) versus the thickness of the epithelium (z_max). (B) The value d₂ versus stratification factor (SF) of stem cells (blue) and TA cells (red). (C) Relationship between d₂ and the total stem cell (left) and TA cell (right panel) populations (arbitrary unit). (D) Cell distributions with d₂ = 0.01, 0.1, and 1. All other parameters are listed in Table S1 and Table S2.
