Maximal density and total amount of progenitor cells on a crypt as functions of removal rate of BMP or maximal death rate of TD cells. (A) Blue: removal rate of BMP versus maximal density of progenitor cells (max (C0)); green: removal rate of BMP versus total amount of progenitor cells. (B) Blue: maximal death rate of TD cells (d¯1) versus maximal density of progenitor cells (max (C0)); green: maximal death rate of TD cells versus the total amount of progenitor cells. (C) Spatial distribution of progenitor cells and the spatial crypt pattern at d¯1=0.02 and 0.2. Other parameters used for the simulation are in Additional file 1: Table S2.
