Figure 2: Membrane deformations induced by actin assembly. A membrane bilayer (pink) constituting an initially spherical liposome is deformed through the growth of a branched actin network (blue marks the colour of the end of actin filaments) at its surface. Spikes (inward) and tubes (outward) are formed during this process. Note that compared to the cell geometry, the geometry here is inside out, as the ingredients of the cytoskeleton are outside the liposome. Bar 5 μm. Copyright: Cécile Sykes, CNRS
