this study demonstrates that the shift of these thy-1+ nk cells to thy-1- nk cells is influenced by the thymus : nk cells developing in the total absence of the thymus -- bone marrow ( bm ) cells from adult thymectomized ( tx ) or nude ( nu ) mice injected into thymectomized recipients , ( tx ) bm -- -- ( tx ) or nu bm -- -- ( tx ) -- remain thy-1+ , while the presence of the thymus at some stage of the nk cell maturation -- bone marrow cells injected into thymectomized recipients , bm -- -- ( tx ) , or normal recipients reconstituted with bone marrow cells from thymectomized or nude mice , ( tx ) bm -- -- or nu bm -- -- normal recipients -- is sufficient for the development of normal ratio of thy-1+ and thy-1- nk cells .
