title: F-actin is involved in the polyethylene glycol-induced fusion of chick embryo fibroblasts.
abstract: Cytochalasin B inhibits the polyethylene glycol (PEG)-induced fusion of chick embryo fibroblasts. Induction of fusion of these cells by PEG is associated with transient changes in the pattern of F-actin organization within the cell. The changes include the disappearance of stress fibres and accumulation of F-actin under the plasma membrane. These results suggest an involvement of F-actin in PEG-induced cell fusion.
