ABSTRACT:
A device for controlling cell arrangement having a pattern composed of a cell adhesive surface and a cell non-adhesive surface, which has a good selectivity of cell adhesion and which can provide a fine pattern of cells in high resolution by culturing cells in a usual manner. The device is prepared by a process which comprises applying a photosensitive, cell adhesive or cell non-adhesive polymer to a surface having a reverse cell adhesivity property to that of the applied polymer, and patternwise irradiating a light to the photosensitive polymer layer followed by development; a process which comprises patternwise irradiating UV or radiation to a cell non-adhesive surface to produce a cell adhesive functional group such as carboxyl group or amino group in the irradiated portion; or a process which comprises patternwise irradiating UV or radiation to a cell adhesive or non-adhesive surface made of plastics to produce a polymerization initiation site in the irradiated portion, and graft-polymerizing at least one monomer having the reverse cell adhesivity property to the plastic surface to produce a polymer on the irradiated portion of plastic surface.
