[Self-maintenance of migrating hematopoietic stem cells].

Decreased self-maintenance ability of the migrating stem cells (CFU) from the peripheral blood or ectopic focus of hemopoiesis in comparison to the settled bone marrow CFU, as measured by the spleen colony method or by means of chromosomal markers, has been studied. The competence for myeloid and lymphoid differentiation was essentially the same for migrating and settled stem cells.
