Cytoskeletal actin and nonmuscle myosin II in fibroblasts
Previous Image | Next Image
Description: a) Actin fibers as detected by fluorescent phalloidin, which binds specifically to actin.

b) Myosin in the same cell detected by an injected fluorescent antibody.

c) A mechanism for contractility in the cytoskeleton. An NM II filament (green and olive) will bring together two anchored actin microfilaments (red). NM II moves toward the “+” end of the microfilament.

d) The direction of movement of the actin microfilaments is shown by the arrows.
