Abstract
A method of screening for a substance that acts on a cell mass includes producing a cell mass by three-dimensional culture of primary cancer cells using a tumor tissue, adding a test substance to the cell mass, and evaluating an action of the test substance on the cell mass. The cell mass is produced by culturing cells obtained from the tumor tissue in a medium containing a 5% v/v or less extracellular matrix on a substantially low-adhesive cell culture substrate and producing the cell mass of the primary cancer cells.
