Background Osteosarcoma (OS) is one of the most common primary malignant bone tumors, primarily originating from mesenchymal tissue. It notorious for its high invasiveness, disability rate, mortality and poor prognosis. In metastatic destruction can promote cancer progression, which closely related to osteoclast activation imbalance between osteoblasts osteoclasts. A large number studies confirmed that osteoclasts are an important part OS, play active role in destroying homeostasis promoting progress OS. Therefore, we conducted a detailed study at single cell level, aiming find new OS therapeutic targets prevent tumor progression local spread.
