Abstract
A gut organoid includes a tissue structure that encloses a cavity. A method of using the gut organoid includes providing a test drug to the gut organoid in the presence of a buffer solution so that liquid comprising the test drug enters into the cavity, and collecting and analyzing the liquid in the cavity. A method for producing the gut organoid includes plating cells on a cell culture substrate including a surface on which a cell-adhesive region and a non-cell-adhesive region surrounding the cell-adhesive region are formed, and culturing the cells plated on the cell culture substrate so as to induce differentiation of the cells.
