IDENTIFICATION OF MARROW-DERIVED AND THYMUS-DERIVED SMALL LYMPHOCYTES IN THE LYMPHOID TISSUE AND THORACIC DUCT LYMPH OF NORMAL RATS

Abstract
These experiments show that small lymphocytes from the thoracic duct of rats are normally a mixture of thymus-derived and marrow-derived cells, and define the traffic areas in lymphoid tissues through which the two populations recirculate.
