Fig. 4: Three different sub-domains within lamellipodia.
From: A network of mixed actin polarity in the leading edge of spreading cells

a A color scheme indicating the angles between actin filaments and plasma membrane (turquoise). b–d Surface rendered views of representative tomograms from the 3 different sub-domains with the actin filaments colored according to their orientation with respect to the plasma membrane. Scale bar: 300 nm. e–g The fraction of the forward (blue), parallel (mustard), and backward (red) actin orientations as a function of the distance from the membrane are plotted as continuous lines, with a shaded error bar of data standard deviation, for protruding, transition, and resting sub-domains (N = 10, 16, 21 tomograms).
