Abstract: A Micro-Well Array Plates (MWAP) assembly for high throughput microfluidic devices for studying cells and method of manufacturing thereof are provided. The MWAP assembly includes a top plate having a plurality of macro-wells arranged in an array within a frame. The MWAP assembly also includes a bottom plate operable to be secured to the bottom surface of the frame, the bottom plate having a plurality of arrays of micro-wells. The MWAP assembly includes a well grid formed when the bottom plate is secured to the top plate via the plurality of macro-wells and the plurality of arrays micro-wells. The well grid with the plurality of macro-wells and the plurality of arrays micro-wells enable visualization of cells via a high throughput.

Abstract: A Cell Migration Assay Plates (CMAP) assembly for high throughput microfluidic migration assays and method of manufacturing thereof are provided. The CMAP assembly includes a top plate having a plurality of wells aligned with a bottom plate having a plurality of troughs. Each of the plurality of wells is defined at least in part by first and second reservoirs and a divisional wall extending between the reservoirs. The bottom plate is secured to the top plate to form a plurality of micro-channels, such that each one of the plurality of micro-channels is defined by a portion of one of the divisional walls and a portion of a corresponding one of the plurality of troughs. The plurality of micro-channels enable communication between the reservoirs and visualization of cells migrating through the micro-channels. In this manner, migration of cells through the micro-channels can be visualized for testing and screening applications.

Abstract: A material comprising a plurality of closed cells is provided, the space within each cell being substantially evacuated. This may be achieved by sealing a dimpled film to a sealing film in a vacuum so that each dimple is closed while under vacuum to form an evacuated closed cell.

Abstract: The invention provides chimeric non-human animals, methods for making and using chimeric non-human animals, isolated stem cells, and methods for identifying agents that reduces cancer in a non-human animal. For example, the invention relates to using stem cells to make chimeric non-human animals having cancer or the ability to develop cancer. Such animals can be used to evaluate tumorigenesis, tumor maintenance, and tumor regression in vivo. In addition, the chimeric non-human animals provided herein can be used to identify agents that reduce or prevent tumor formation or growth in vivo.
