To evaluate directly the developmental potential of cortical CD4+8+ thymocytes, highly purified populations of small, nondividing CD4+8+TCRlow and large, dividing CD4+8+TCRhigh thymocytes from H‐2d mice expressing a transgenic T cell receptor restricted by H‐2Db (major histocompatibility complex class I) molecules were transferred into the thymus of normal, nonirradiated H‐2b recipient mice. The results show that both populations generate CD48+ thymocytes under these conditions, thus providing conclusive evidence that small cortical thymocytes do not represent a “dead end” but an important intermediate stage in T cell development.
