The reconstitution of B cells in the bone marrow and peripheral blood was prospectively studied in 27 patients undergoing autologous bone marrow transplantation (ABMT). No major differences in B cell regeneration patterns were recorded between patients receiving marrows purged of B cells (anti-CD10 + 19; n = 17) and patients receiving unpurged marrows (n = 10). Compared with healthy controls, elevated absolute and relative numbers of B cells were recorded in the blood and marrow at +6 and +12 months in both groups of patients. CD23+ B cells were severely depressed during the first three months post ABMT, indicating immaturity. A twofold increase in B cells carrying the activation marker 4F2 was recorded in the marrow at +1 month. Serum immunoglobulin levels (IgG, IgA, IgM) were within low-normal range throughout the study. The depressed B cell responses reported after allogeneic and autologous BMT could in part be explained by the low expression of the CD23 antigen on B cells after such therapy.
