One of my favorite images: a platinum replica electron microscopy shot of an unroofed cancer cell migrating along collagen fibers (blue). It beautifully captures the clathrin-coated pits (red, ~100 nm) and the intricate network of branched actin filaments (orange) 🔬

is there a direct crosstalk between actin and vimentin intermediate filaments? Our work shows that vimentin promotes actin assembly by stabilizing ATP-subunits at the barbed end.
