Powerful Microscope Reveals Motility Nanoscaffold

Cryo-electron microscope images of actin assembly in the cell in the absence of a molecular signal (left) and the haystack-like actin filament nanoscaffold that was induced in response to a molecular signal (Rac1) and promotes cell movement (right). The structure sprang into view in defined regions where Rac1 was activated, and quickly dissipated when Rac1 signaling stopped--in as little as two and a half minutes.
