Abstract

Official abstract text for this publication.

To provide a cell culture method capable of sustaining in-vivo functions for a long time by suppressing dedifferentiation. A cell culture method in accordance with the present invention is to culture cells in a multi-layered state in a minute partitioned space and to obtain a tissue structure having a function resembling an in-vivo function. When the cells are mammary gland epithelial cells, a hollow acinus-like structure can be formed. The minute partitioned space is particularly preferably a micro container in a cell culture container having a plurality of such micro containers on the surface.

First claim

Opening claim text (preview).

The invention claimed is: 1. A cell culture method comprising: culturing cells in a multi-layered state in a minute partitioned space and obtaining a tissue structure having a function resembling an in-vivo function, wherein the minute partitioned space is a micro container in a cell culture container having a plurality of micro containers on a surface, wherein adjacent micro containers are communicated with each other with an opening formed in a sidewall partitioning the adjacent micro containers, and a width of the opening is 3 μm to 20 μm, and wherein the cells are mammary gland epithelial cells. 2. The cell culture method according to claim 1 , wherein the cells are primary cells. 3. The cell culture method according to claim 1 , wherein the mammary gland epithelial cells are differentiated and form a hollow acinus structure. 4. The cell culture method according to claim 1 , wherein a base area of the micro container is 9×10 −4 mm 2 to 9×10 −2 mm 2 ; a height of a sidewall is 15 μm to 300 μm; and a width of a sidewall is 3 μm to 15 μm. 5. The cell culture method according to claim 1 , wherein a region of the cell culture container in which a micro container is formed has transparency.
