hematopoietic system
increased spleen weight ( J:301035 )
• resulting from stress erythropoiesis after Poly(I:C) treatment
abnormal erythropoiesis ( J:301035 )
• adults at 8-12 weeks of age were assessed after being injected with 300 ug Poly(I:C) every other day for 5 days and were found to have suppressed basal erythropoiesis with severe anemia, thrombocytopenia, and leukopenia, with very low CD45- erythroid and CD45+ non-erythroid cell counts in bone marrow, but progression between precursor stages is not affected, and stress erythropoiesis is found with markedly increased spleen size, increased red pulp, increased BFU-E and CFU-E, increased erythroblasts, and reticulocytosis
anemia ( J:301035 )
• profound anemia after Poly(I:C) treatment
decreased erythrocyte cell number ( J:301035 )
