title: Thymopoiesis in 4 dimensions.
abstract: Developing T cells undergo long-range migrations in the thymus that are tightly linked to their developmental program. In this review, we discuss the anatomical positioning of developing T cells in the thymus, review what we know about how cells move in the thymus, and point out unresolved questions. We also discuss new imaging technologies and interdisciplinary approaches and discuss how the promise they offer to addressing these questions.
