Migration and invasion assay.

<p>Caski-miR155 and Caski cells were seeded in Transwell inserts with or without Matrigel. The inserts were fixed and stained after 24 hours, and then the migratory/invading cells were counted under a microscope. The number of Caski-miR155 cells passing through the membrane was significantly lower than that in the normal Caski cells, whether detected by migration or invasion assays. Values are the average of triple determinations with the S.D. indicated by error bars. *P<0.05.
