[Stem cells and T- and B-lymphocytes in acute hypoxia]

During the stepped rapid training of mice for hypoxia the number of colony-forming units in the blood and bone marrow increases and that in the spleen falls down. In acute hypoxic hypoxia there is an enhancement of the migration of stem hemopoietic cells and B-lymphocytes from the bone marrow and T-lymphocytes from the thymus.
