Abstract

In density-inhibited 3T3 fibroblast cultures F-actin is localized almost exclusively at the cell-to-cell borders. Depolymerization of microtubules results in a rearrangement of the F-actin pattern. Numerous actin bundles are formed, most of them are anchored to the cell borders. This rearrangement is preceded by a transient rise in F-actin content.
