hematopoietic system
• at day 450, blood smears of some mice display numerous immature myeloid progenitor cells in clumps and with a high nucleus to cytoplasm ratio
• the erythroid precursor compartment in the spleen and marrow is increased
at day 450, 4- to 6-fold more splenic erythroid precursors remain in S phase
• in 5% of mice blood smears are fibrotic
|
• extramedullary hematopoiesis occurs in the spleen, liver and lungs via aggregates of plasma cells
|
• at day 400, erythroid progenitor cells contain abnormal mitotic figures, abnormally high nucleus-to-cytoplasm ratios, and increased levels of monocytes and ring granulocytes
• in 5% of mice blood smears are fibrotic
|
• at day 400, the bone marrow is hypercellular
|
• at day 450, some mice display dysplastic erythrocytes characterized by echinocytosis
|
• at day 450, mice suffer from lymphopenia
|
• at day 450, white blood cell counts are elevated
|
• at day 100, granolycyte number is increased
• at day 400, the bone marrow contains increased numbers of ring granulocytes
|
• at day 100
|
• at day 400, the bone marrow contains increased levels of monocytes
|
• at day 100, spleen dysplasia is apparent
• congestion and necrosis are observed in the spleen
|
• at 450 days
|
• mice lack or have malformed germinal centers
• at day 100, hemosidirin levels are elevated and there is marked congestion, necrosis and extramedullary hematopoiesis via aggregates of plasma cells
