Abstract: The establishment and growth of metastatic tumors can be detected and inhibited by the methods and compositions described herein. As illustrated herein, agents that inhibit the expression or activity of versican, for example, in bone marrow cells effectively halt the growth and establishment of metastatic tumors at distal sites from a primary tumor site. In general, the primary tumor is unaffected by versican inhibitors but metastasis is substantially eliminated.
