FROZEN CELL IMMOBILIZED PRODUCT, PRIMARY HEPATOCYTE CULTURE TOOL, AND METHOD FOR PRODUCING PRIMARY HEPATOCYTE CULTURE TOOL

摘要

The present invention provides a frozen cell immobilized product which is obtained by applying a technique for freezing cultured cells to a technique for forming primary hepatocyte spheroids through co-culturing, and which can improve performance in an examination or a test using the technique for forming primary hepatocyte spheroids; a primary hepatocyte culture tool; and a method for producing the primary hepatocyte culture tool. According to the invention, a cell-adhesion region of a culture substrate is defined in a pattern; animal-derived adherent cells are cultured on the cell-adhesion region; and the cultured cells are frozen together with a freezing culture medium.
