Fig. 2. Perturbation of any single cytoskeletal system in unfixed samples does not
prevent interaction of the remaining two. Triple label confocal micrographs
showing that inhibition of F-actin (green) fails to prevent cytokeratin (blue)
association with aster microtubules (red) (latrunculin, arrows); inhibition of
cytokeratin polymerization does not inhibit F-actin association with aster
microtubules (C11, arrows); inhibition of microtubule polymerization does not
prevent interactions between F-actin and cytokeratin (nocodazole, arrows).
