Dividing walls: How immune cells enter tissue

To get to the places where they are needed, immune cells not only squeeze through tiny pores. They even overcome wall-like barriers of tightly packed cells. Researchers at the Institute of Science and Technology Austria (ISTA) have now discovered that cell division is key to their success. Together with other recent studies, their findings published in Science give the full picture of a process just as important for healing as for the spread of cancer.
