Actin filament density controls the growth rate of branched actin network. a Images of typical LMs of variable filament density reconstituted on bar-shaped patterns of constant geometry and variable NPF concentration. The images taken after 78 min of actin assembly reveal that denser networks grew slower than the sparser ones. b The network density was measured across the LMs (along the white line as indicated in a, left image). c Network growth rates at 20 min were represented as a function of the network fluorescence. Simulated growth rates at 20 min (red solid line) were calculated as a function of computed filament densities and according to the measured parameter Φ = 0.7 (Fig. 1; Supplementary Methods). Scale bars are 15 µm (see also related Supplementary Fig. 8)
