Multiple myelоmа bоne diseаse is chаracterized by exacerbated bоne resorption and the presence of osteolytic lesions that do not heal because of a reduction in bone formation. Multiple myeloma directly affects the molecules of the bone cells that regulate both bone formation and resorption. Recent findings suggest that the life span of the bones cells that monitor and maintain the bone tissue is compromised in multiple myeloma patients with bone lesions. Further, patients with active multiple myeloma have elevated circulating levels of sclerostin, a potent inhibitor of bone formation which is specifically expressed by the bone cells that maintain bone matrix. Multiple myeloma bone disease exacerbates (increases) bone resorption. What bone cell type is most likely responsible for this increase in bone resorption?
