Thymic emigration: conveyor belts or lucky dips?

Abstract

The thymic medulla has always seemed a rather uncomplicated compartment, simply storing mature thymocytes until they are exported to the peripheral lymphoid organs. However, as discussed here by Roland Scollay and Dale Godfrey, a careful look at recent data suggests that events in the medulla may be more complex and protracted than previously thought. © 1995 Elsevier Science Ltd.
