Document Type and Number:
WIPO Patent Application WO/2021/029241
Kind Code:
A1
Abstract:
Provided are a cell culture substrate that can be prepared easily and also permits cell culture to be carried out efficiently, a method for producing the substrate, a method for culturing cells using the substrate, and a method for producing spheroids using the substrate. A cell culture substrate having a layer that has a cell adhesive surface, and a fine pattern of a cell non-adhesive material provided on the surface of the layer, the cell adhesive surface being the cell culture surface. Additionally, a method for producing a cell culture substrate, the method including a step for printing a cell non-adhesive material to form a fine pattern on a layer having a cell adhesive surface.
