Abstract

Using the Matrigel invasion assay, we have examined the role of cell adhesion and migration in the invasiveness of two cell lines, DM and HSR, derived from the Y1 mouse adrenocrotical tumor. The DM cells were metastatic and more invasive (10-fold) than the nonmetastatic HSR cells. The difference in invasiveness could not be ascribed to different levels of secreted type IV collagenolytic activity since HSR cells secreted higher levels of activity. Cells from the metastatic DM line showed greater motility to both laminin and fibronectin when compared to the HSR line. Furthermore, both Matrigel and laminin promoted the attachment and spreading of DM cells but they had little effect on the adhesion of the HSR cells. Electron microscopic examination revealed an increased ruffling of the cell membrane in the metastatic DM line. These studies suggest a role for cell adhesion and migration on the invasion of Matrigel by malignant tumor cells.
