Abstract
Methods and a device are provided for adhering cells in a specific and predetermined position. The device comprises a plate defining a surface and a plurality of cytophilic islands that adhere cells which are isolated by cytophobic regions to which cells do not adhere. The cytophobic regions can be wide enough such that less than 10 percent of the cells adhered to the cytophilic islands are allowed to form bridges across the cytophobic regions and contact each other. Further, the islands or the regions or both may be formed of a self-assembled monolayer (SAM). The methods are for forming a patterned surface for a population of cells and for selectively manipulating individual cells formed on the surface of the plate of the device. Furthermore, the device is used in immobilization of cells at a surface and for controlling shape of the cells.
