Abstract
An object of the present invention is to provide a technique for precisely arranging nerve cells on a substrate while suppressing the migration of nerve cells. A manufacturing method for a substrate on which nerve cells are arranged is provided, the method including a step of arranging, on a substrate, a plurality of liquid droplets containing nerve cells by an inkjet method to form one or a plurality of liquid pools, the substrate having a region in which a cell adhesive material is arranged and a region in which a cell non-adhesive material is arranged; and a step of incubating the liquid pool until the nerve cells sediment and temporarily adhere onto the substrate to form a cell aggregate. The diameter per one liquid pool is 500 μm or less, and the density of nerve cells per one liquid pool is 10cells/cmor more.
