Impact of correlated aster birth–death dynamics on transport results

Determine whether spatially correlated creation and annihilation of cortical actin asters qualitatively alters the temperature independence of the transport coefficient D(T) predicted by the active-membrane lattice model.

Background

The active lattice model assumes uncorrelated aster creation and annihilation at fixed area fraction and shows temperature-independent transport under these assumptions. Varying aster size without changing area fraction did not qualitatively affect results.

The authors note uncertainty about whether introducing correlated spatial birth–death dynamics of asters could qualitatively change transport behavior.
