• at 8 months, 7 of 10 mice exhibit focal osteolytic lesion mainly in the hind limb unlike wild-type mice
• at 12 months, 20 of 21 mice exhibit focal osteolytic lesion mainly in the hind limb unlike wild-type mice
• however, young mice exhibit normal trabecular bone density and structure
|
• 3 of 20 osteoclasts from bone lesions exhibit nuclear inclusions unlike wild-type cells
• osteoclasts that differentiate from bone marrow macrophage are larger and contained more nuclei than osteoclasts that differentiate from wild-type macrophage
|
• osteoclast formation from bone marrow macrophages is increased compared to from wild-type bone marrow

|
• mice exhibit increased mineral apposition rate and mineralizing surface within bone lesions compared with wild-type mice
