'Velcro protein' found to play surprising role in cell migration

Studying epithelial cells, the cell type that most commonly turns cancerous, Johns Hopkins researchers have identified a protein that causes cells to release from their neighbors and migrate away from healthy mammary, or breast, tissue in mice. They also found that deletion of a cellular "Velcro protein" does not cause the single-celled migration expected. Their results, they say, help clarify the molecular changes required for cancer cells to metastasize.
