Summary A codominantly inherited mutation of the lactate dehydrogenase (LDH) in the C3H mouse causes a severe hemolytic anemia in homozygous mutants, whereas viability and fertility are close to normal. Investigation of multipotent hemopoietic stem cells (CFU-S), myeloid (GM-CFC) and erythroid progenitors (BFU-E, CFU-E) in femur and spleen indicates a general shift from bone marrow to splenic hemopoiesis. In terms of total body hemopoiesis, however, the BFU-E pool is 1.4- and the CFU-E pool 19-fold enlarged, whereas CFU-S and GM-CFC show little or no deviation from normal. It is concluded that this mouse mutant is an appropriate model of long-term hemopoietic stress showing that compensation in this severe hemolytic anemia is achieved primarily by an increase of the number of the most mature erythroid progenitors.
