From: A ‘dynamic adder model’ for cell size homeostasis in Dictyostelium cells
Cell surface area in Dictyostelium cells is regulated by an adder or near-adder model. (A–C) Ideal graphs to assess the three models to explain the regulation of cell size homeostasis. (A) The added surface area during cell cycle versus the cell surface area at birth. (B) The cell surface area immediately before cytokinesis versus the cell surface area at birth. (C) The logarithmic generation time versus the logarithmic cell surface area at birth. Cave and Tave show the average cell surface area at birth and the average generation time, respectively. (D–F) Graphs of actual data in a whole cell cycle (Whole). (G–I) Graphs of actual data between the first cell division and immediately before mitosis (Interphase). (J) A graph of actual data during cell division (M phase). In graphs D–J, the red lines show results by linear regression. The blue vertical lines show the binned mean ± SD.
