Fig 9. Effect of cellular growth on structure size control.

(A,B) In the limiting pool model (α + β = 0), fast structure growth shows characteristic large fluctuations and loss of size control. In the slow growth regime, transient size control is observed without significant size fluctuations (B, Inset) With difference in growth rates of the structures (e.g., here κ₁ = 2κ₂), a winner-takes-all dynamics ensues and the structure with larger growth rate (blue) increases in size, while the other structure (red) remains small in size. (C,D) The size-dependent growth model (α + β = 1) provides local temporal control of structure size, with the structure size growing at the same rate as cellular growth.
