Abstract
Cytochalasin B prevents both migration and wound-associated replication when applied to wounded monolayers of bovine endothelium in tissue culture. The normal low background rate of replication in undisturbed areas of the cultures is not inhibited by cytochalasin B. These results suggest that some form of movement may be required for initiation of wound-associated replication by endothelial cells.
