Patent ID: 7033819

Claim:
A system for monitoring cell movement comprising: a) a device for arraying cells b) an observation system configured to observe movement or lack of movement of arrayed cells; and c) a controller configured to link movement of the device for arraying cells into said observation system, the device for arraying cells comprising (i) a support; (ii) a first layer configured to be placed in fluid-tight contact with the support, the first layer having an upper surface and defining a pattern of micro-orifices, each micro-orifice of the pattern of micro-orifices having walls and defining a micro-region on the support when the first layer is placed in fluid-tight contact with the support such that the walls of said each micro-orifice and the micro-region on the support together define a micro-well; (ii) a second layer configured to be placed in fluid-tight contact with the upper surface of the first layer, the second layer defining a pattern of macro-orifices, each macro-orifice of the pattern of macro-orifices having walls and defining a macro-region when the first layer is placed in fluid-tight contact with the support and the second layer is placed in fluid-tight contact with the first layer such that the walls of the macro-orifice and the macro-region together define a macro-well wherein each macro-region encompasses at least one micro-region; wherein the first layer and the second layer are configured for an arraying of cells on the support through the pattern of micro-orifices and the pattern of macro-orifices; wherein the cells are allowed to grow to confluency within the micro-regions; wherein at least one of a plurality of test agents is provided to at least one macro-well and allowing said test agent to contact confluent cells; wherein said first and second layer are removed; wherein cells are monitored for movement or lack of movement away from said micro-regions; and correlating cellular movement or lack of movement away from said micro-regions with effect of said test agent on cellular movement.
