Abstract

A new means of separately arranging individual animal cells on a substrate surface is provided. A method for preparing a substrate for arranging animal cells in an array, comprising steps (1) to (3): (1) preparing a substrate having adsorption surfaces in an array on an electrode substrate surface; (2) causing an extracellular matrix to adsorb to the electrode surface and the adsorption surfaces of the substrate; and (3) applying a weak potential to the electrode to cause the extracellular matrix on the electrode surface to separate to obtain a substrate with the extracellular matrix adhered to the adsorption surfaces thereof. A method for preparing a substrate on which animal cells have been arranged in an array, comprising steps (1) to (4): (1) preparing a substrate having adsorption surfaces in an array on an electrode substrate surface; (2) causing an extracellular matrix to adsorb to the electrode surface and the adsorption surfaces of the substrate; (3) applying a weak potential to the electrode to cause the extracellular matrix on the electrode surface to separate to obtain a substrate with extracellular matrix adhered to the adsorption surfaces thereof; and (4) culturing the animal cells on the surface of the substrate obtained in (3) to obtain a substrate on which the animal cells have adhered to the adsorption surface.
