mortality/aging
premature death ( J:163407 )
• nearly half (15 of 33) of the mice died between 14?51 weeks after birth

neoplasm
increased tumor incidence ( J:163407 )
• a markedly high incidence (24 of 41) of large cell tumors at 65 weeks of age
increased histiocytic sarcoma incidence ( J:163407 )
• abnormal proliferative cells with histiocytic morphology and cell surface markers in the bone marrow, spleen, and/or liver
• the histiocytic sarcoma is highly invasive and transplantable

hematopoietic system
increased macrophage cell number ( J:163407 )
• abnormal Mac-2-positive macrophages in the lung
abnormal macrophage physiology ( J:163407 )
• bone marrow-derived macrophages at 10-12 weeks of age stimulated with M-CSF and GM-CSF, show an increased proliferative response

immune system
increased macrophage cell number ( J:163407 )
• abnormal Mac-2-positive macrophages in the lung
abnormal macrophage physiology ( J:163407 )
• bone marrow-derived macrophages at 10-12 weeks of age stimulated with M-CSF and GM-CSF, show an increased proliferative response
