New tool reveals secrets of migrating cells

...t do. The scenario they've reconstructed from the video and mathematical analysis starts with immature T cells moving out of the center of the thymus, the medulla, to the very outside edge of the cortex, where they proliferate and fill up the cortex. At this point, Witt said, they undergo the first of two...
