• 11-14% longer than controls at 40 days of age

skeleton

• 14 cartilaginous nodules in epiphyseal cavities of femurs from 9 mice

• have a distended and fragmented endoplastic reticulum
• cartilaginous nodules in bone marrow cavity
• cartilaginous nodules in epiphyseal cavities
• non hypertrophic cartilagenous clusters penetrating the bone marrow cavity become hypertrophic and gradually form pseudogrowth plates
• growth plates are essentially normal embryonically
• neoplastic clusters penetrate through the hypertrophic zone into the bone marrow cavity

neoplasm
• clusters of "resting" chondrocytes develop into neoplastic cores by day 5
• clusters become more distinct by day 7 and migrate toward epiphyses

behavior/neurological
• progressive hind limb paralysis results in death by 18 months

immune system
• 6-month-old mice exhibit cartilage destruction which becomes severe at 18 months of age indicating spontaneous age-related osteoarthritis
• cartilage destruction is accompanied by aggravated synovial inflammation but comparable osteophyte maturity as in controls
• expression of senescence, DNA damage, and catabolic markers are decreased in cartilage of aged mice
• however, mice exhibit normal skeletal development, with normal organization of growth plates and normal body weight
