title: Immunofluorescent detection of actin cytoskeleton in spontaneously transformed and B77-supertransformed cells using antibody to tropomyosin.
abstract: Differences in immunofluorescence of actin cytoskeleton between normal rat fibroblasts and two transformed cell lines SAMIV and SAMB77 were detected by antiserum to tropomyosin. In both transformed cell lines reduction in number and shortening of microfilament bundles (stress fibers) were observed. In some transformed cells ruffling membranes (peripheral ruffles) were seen. Differences were found in actin cytoskeleton among individual cells of spontaneous transformants (SAMIV) and supertransformants (SAMB77).
