During the first 3 days after irradiation and reconstitution (IR) with hemopoietic stem cells a small number of cells with the capacity to form colonies (CFU-s) can be detected in the thymus. This number is increased when thymectomized mice are used as recipients for colony determination. In thymus-cell suspensions from animals 4 days after IR no CFU-s can be found either in normal or in thymectomized recipients. Tracer studies with 111In-labeled oxine revealed that thymocytes obtained from animals 3 days after IR contain a large number of cells with a strong preference for the thymus. This number decreases in the following days after irradiation; these cells are thought to represent an intermediate cell between stem cell and T cell.
