Abstract
When the marrow and spleen cells of plethoric mice are cultured with 1.0 unit/ml of limulus-lysate-absorbed Ep, the predominant erythroid progenitor cell assayed is the Day 3 BFU-E. Erythropoiesis by these cells can be studied by enumeration of bursts at 3 days or by 24-hr 59Fe incorporation into heme. Endotoxin markedly increased the number of Day 3 BFU-E in the spleens of these mice and decreased the number in the marrow, but it had little effect on erythropoietic maturation. In contrast, Ep produced differentiation of the erythroid progenitor cells resulting in increased splenic CFU-E and a decline in the more primitive erythroid precursor cells.
