Migration of hepatocellular carcinoma (HCC) cells that have undergone epithelial to mesenchymal transition (EMT). The 3sp cells transdifferentiated from malignant hepatocytes in the HCC patient via EMT show a migratory potential as determined by Platypus technology that can be modulated by pharmacological interference. Migrating cells are visualized by staining with CellTracker. For details, see article by van Zijl and colleagues on page 850.
