The bone marrow of young adult nude mice was investigated as a site of antibody formation after intravenous immunization with the thymus-independent antigen Escherichia coli lipopolysaccharide (LPS). Mice heterozygous for the nu-gene were found to be capable of a plaque-forming cell (PFC) response in both spleen and bone marrow after primary and secondary immunization with LPS. Primary immunization of nude mice with LPS induced a normal PFC response in the spleen, but did not evoke the appearance of PFC in the bone marrow. During the secondary response the nude mice did show PFC activity in the bone marrow, but at a much lower level than their heterozygous littermates. At all time points after secondary immunization the number of splenic PFC was higher in nude mice than in the control mice.
