From: A ‘dynamic adder model’ for cell size homeostasis in Dictyostelium cells
Dynamic adder model. (A) A previous adder model considered only the added surface area without taking into account the turnover of cell membrane. Here, ΔS is the total added surface area, and ΔSEXO is the added surface area due to exocytosis. (B) Since the cell membrane rapidly turns over, the total added surface area (ΔS) should be determined by subtracting the amount of membrane uptake by endocytosis (ΔSEND) from that of membrane supply by exocytosis (ΔSEXO). (C) A summary of the dynamics of the total cell surface area in a whole cell cycle of Dictyostelium cells.
