T-lymphocyte colonies were cultured using lymphocytes from patients with aplastic anaemia and normal donors to assess their respective proliferative activities. Colony numbers from aplastic patient's cells were lower than from normal donors', though this was not significant. When lymphocytes from patients were co-cultured with normal lymphocytes, inhibition of T-colony formation was observed in 8 out of 12 experiments. As the degree of inhibition was greater than if patient cells grew no colonies, then, clearly, normal T-colony formation was inhibited. This ability of patients' lymphocytes to suppress lymphopoiesis might account for the low levels of patient T-colony formation, as well as low in vivo numbers of lymphocytes found in patients with aplastic anaemia. The role of patients' lymphocytes in causing marrow aplasia was investigated. Although the incorporation of patients' lymphocytes in normal granulocyte-macrophage (GM) colony-forming systems inhibited colony growth, in only 1 out of 8 patients was this inhibition significantly greater than that caused by the addition of normal lymphocytes to GM colony systems. Therefore, lymphocytes may not be the primary cause of aplastic anaemia, except for a few rare cases.
