hematopoietic system
N
• at 3 and 6 months of age mice are not anemic despite disrupted iron homeostasis
• at 6 months of age, reticulocytes and mature erythrocytes have reduced cellular hemoglobin
• at 12 months of age hemoglobin content of erythrocytes remains reduced compared to wild-type controls
• at 6 months of age, reticulocytes and mature erythrocytes have reduced cell volume
• at 12 months of age mean cell volume of erythrocytes remains reduced compared to wild-type controls
• at 12 months of age spleen iron content is increased compared to controls

homeostasis/metabolism
• at 12 months of age spleen iron content is increased compared to controls
• significant reduction in liver non-heme iron at 6 and 12 months of age

immune system
• at 12 months of age spleen iron content is increased compared to controls

liver/biliary system
• significant reduction in liver non-heme iron at 6 and 12 months of age
