Fresh and cryopreserved autologous or allogeneic mononuclear blood cells (MBCs) intravenously injected in 1200 R total-body x-irradiated dogs repopulated lymph nodes within 10 days after transfusion. Several parameters of the lymphopoietic regeneration were correlated with the number of cells transfused and with the number of colony-forming units contained in the cell suspension when they were cultured in agar (CFU/sub c/). Values within the normal or close to normal range were reached in the mesenteric nodes of most of the animals transfused with 10 x 10/sup 9/ MBC or more. These values were obtained when 5 x 10/sup 5/ CFU/sub c/ or more were transfused. Axillary nodes showed lower values than mesenteric nodes. They were mostly under the normal range but well over those of the irradiated controls. Frozen and thawed MBCs seem to be as effective as fresh cells for lymphopoietic restoration. The mesenteric nodes of dogs transfused with allogeneic MBCs showed higher cellularity and larger cortical-paracortical areas than those of dogs transfused with approximately the same number of autologous cells. The repopulation of lymph nodes parallels that of the marrow.
