    Abstract: The present invention relates to an indirect three-dimensional co-culture. The indirect co-culture may comprise bone marrow niche cells, tumor cells and a culture medium. The bone marrow niche cells and the tumor cells may be incubated in the culture medium without direct contact between the bone marrow niche cells and the tumor cells. The tumor cells may be dormant or reactivated. Also provided are a method for preparing the indirect co-culture and a method for screening for an agent capable of inhibiting reactivation of dormant tumor cells or promoting dormancy of proliferating tumor cells.
