Extracellular matrix triggers a directed cell migratory response in sea urchin primary mesenchyme cells.

???displayArticle.abstract???
The role of extracellular matrix in cell migration has generally been considered in terms of a substratum. However, when thin cell processes from migrating sea urchin primary mesenchyme cells contact small latex beads coated with extracellular matrix from the blastocoel, the cells migrate directly to the coated beads. Since the beads are not anchored, this result indicates that highly localized contact with the extracellular matrix can stimulate movement independently of any change in cell adhesion.
