Bone tumorigenesis nd abundant osteoclasts in Prkar1atm1.2Lsk/Prkar1a+ Tg(Col1a1-cre)1Kry/0 mice

neoplasm
• mice develop bone tumors starting at 10 weeks of age, with most mice having tumors by 40 weeks of age
• lesions grow slowly, with 25% of mice having 8-mm tumors by 50 weeks of age
• mice do not develop metastases
• lesions are not typical osteosarcomas as they are not composed of malignant osteoblasts depositing osteoid, but consist of an enlarged marrow space filled with abundant myxoid matrix, containing small fibroblast-like cells surrounded by trabecular-like bone, lined by normal osteoblasts and regions with abundant osteoclasts

• bone within and around lesions is normal and contains osteocytes but is undergoing extensive remodeling
