Alteration of Bone Marrow-Thymus Cell Synergism in Hereditary Asplenic and Adult Splenectomized Mice

Abstract
The cooperation betweeen bone marrow (B) and thymus (T) cells was markedly impaired in mice with congenital asplenia. The deficiency of IgM producers could not be corrected by neotal transplantation of spleen cells. The use of T and B cells from splenectomized donors resulted in a marked shift from 19S to 7S antibody forming cells.
