Cell invasion assay of CD133+/CD44+ DU145 cells. CD133+/CD44+ cells isolated from DU145 cultures have increased migratory and invasive capacities. (A) Parental DU145 cells, (B) CD133+/CD44+ cells, (C) CD133+ /CD44+ cells showing a 4-fold increase in the number of cells migrating through a Matrigel-coated membrane compared to parental cells (CD133+/CD44+ cells versus the parental cells, 416 ± 47 versus 109 ± 24, * p < 0.001).
