| Research Abstract |
Prognosis of patients suffering osteosarcoma depends on lung metastasis. Recently the role of bone marrow in the establishment of metastasis shed lights. In this study, we firstly reported the mechanism of change in the cellular motility and motile mode during the osteoblastic differentiation of mesenchymal stem cells-origin of osteosarcoma. Next, we compared the ability of lung metastasis between highly metastatic mouse osteosarcoma cell line, LM8-establisged in our laboratory, and parental Dunn cells. Neither LM8 nor Dunn found in the mouse bone marrow, while striking difference exist during the step of extravasation (invasion onto the endothelial cells of lung) between two cell lines. We thus reported the involvements of invasive ability to establish lung metastasis in mouse osteosarcoma.
