title: Pluripotent haemopoietic progenitor cells (CFU-Sd8) in peripheral blood of hereditarily anaemic Belgrade (b/b) rats.
abstract: The unique anaemic syndrome of the Belgrade laboratory (b/b) rat is due to an intracellular iron deficiency which is induced by a not yet defined mutation, resulting in impairment of haemopoiesis. We investigated the CFU-Sd8 number and concentration in the peripheral blood of b/b rats to study the relationship between medullary and extramedullary haemopoiesis in this anaemic syndrome. The results show normal concentration of CFU-Sd8 in the peripheral blood of b/b rats. This finding was unexpected in the state of severe anaemia and disturbed growth factor production in b/b rats, where the mobilization of CFU-Sd8 from bone marrow to blood is expected. The results suggest that severe anaemia is not regularly accompanied by the mobilization of pluripotent progenitors from bone marrow to the blood.
