Abstract
We describe a new model of myeloma bone disease in which 2m NOD/SCID mice injected with KMS-12-BM cells develop medullary disease after tail vein administration. Micro-computed tomography analysis demonstrated significant bone loss in the tibiae and vertebrae of diseased animals compared to controls, with loss of cortical bone (PPPPPP<0.05) and tibiae of diseased animals, to levels comparable to non-diseased controls. Because of its predominantly medullary involvement and quantifiable parameters of bone disease, the KMS-12-BM xenogeneic model provides unique opportunities to test therapies targeted at the bone marrow microenvironment.
