Hemopoietic recovery in posthypoxic mice: repopulation of CFUs and morphologically identifiable cells in the bone marrow and spleen.

The repopulation of colony forming units (CFU) and morphologically identifiable hemopoietic cells was evaluated quantitatively in the bone marrow and spleen of mice exhibiting enhanced radioresistance after prolonged exposure to hypoxia. Untreated and hypertranfused mice irradiated with the same dose of 300 R served as controls. After irradiation, the immediate decrease in the number of CFUs, myeloid, erythroid, and lymphoid cells was approximately of the same magnitude in all groups of mice studied. However, in animals irradiated after hypoxic pretreatment, the recovery of CFUs and myeloid, but not lymphoid cell compartments, was accelerated. Abortive pattern of myeloid recovery seen in untreated mice was greatly improved. In spite of moderate polycythemia, the repopulation of erythroid cells in the bone marrow, but not in the spleen, was observed during the early postirradiation period. Both the absolute and the relative numbers of CFUs began to rise earlier and the normal values were reached earlier in...
