The cause of the severe anemia in Sl/Sld mice is attributed to (1) hypoproduction of erythrocytes due to a defect in the erythropoietic microenvironment and (2) bleeding from stomach ulcers. Sl/Slt mice also showed a moderate anemia, but bleeding from stomach ulcers was excluded as a cause of the anemia, because no significant amount of radioactivity was excreted in feces after the injection of 59Fe-labeled erythrocytes. The activity of erythropoiesis in the bone marrow and spleen was compared between Sl/Slt and congenic +/+ mice using three different criteria: the number of erythroblasts, 59Fe incorporation, and the number of erythropoietic precursor cells. All three parameters in the femur were lower, and those in the spleen were higher in Sl/Slt mice than in +/+ mice, suggesting that the low erythropoietic potential in the bone marrow of Sl/Slt mice is partially compensated by the spleen. In fact, splenectomy aggravated the anemia of Sl/Slt mice. The enhanced erythropoiesis in Sl/Slt spleens may explain our previous finding that numbers and sizes of spleen colonies were normal when bone marrow cells were injected into irradiated Sl/Slt mice. Sl/Slt mice may be a useful model for studying biological characteristics of the hematopoietic microenvironment.
