MEDYAN: Mechanochemical Simulations of Contraction and Polarity Alignment in Actomyosin Networks
Fig 11
Single trajectory snapshots of the actomyosin systems, with various values of χ after 2000 s of network evolution.
These trajectories are colored with black and white beads for the plus and minus ends of actin filaments, respectively. (A) Low χ, corresponding to a slow turnover rate, produces large global contractions in the absence of polarity alignment. (B) The original turnover rate (χ = 1) produces global contraction as well as polarity alignment. (C) High χ produces no global contraction, but distinct local polarity organization.
