Cell culture method and cell culture apparatus

1. A cell culture apparatus for conducting cell culture comprising:

a container formed of a flexible material and adapted for receiving a culture medium including cells,

a base having a flat mounting surface that holds the container; and

partition pieces that can be protruded from the mounting surface for a prescribed height for partially raising a bottom surface of the container and are embedded in the base,

wherein the base is provided with a holding member that forms the mounting surface and a partition plate on which a plurality of the partition pieces is arranged,

wherein when the partition pieces are accommodated into the base, upper end surfaces of the partition pieces are flush with the mounting surface.

2. The cell culture apparatus according to claim 1 , wherein the plurality of the partition pieces is arranged in parallel with each other with a prescribed interval.

3. The cell culture apparatus according to claim 1 , wherein the base is pivotably supported at one end thereof by a supporting frame such that it can be rotatably moved and due to the rotational operation of the base, after the container is moved to a position higher than the initial position, the container is returned to an initial position by rotatably moving the base as if it falls down and vibration that is due to an impact generated by receiving of the base by the supporting frame is applied to the container returned to the initial position, thereby to stir a content liquid in the container.

4. The cell culture apparatus according to claim 1 , wherein a pressing plate for pressurizing an inside of the container by pressing the container held on the mounting surface is attached such that it can be moved up and down in accordance with an amount of a content in the container.

5. The cell culture apparatus according to claim 4 , wherein annular rising pieces each having an elongated guide hole are vertically provided at each of four corners of the base, and by inserting a pin provided at each of the four corners of the pressing plate into the guide hole, the pressing plate is attached to the base such that it can be moved up and down, and a hook that is engaged with the pressing plate and fixes the pressing plate at a prescribed position is provided.

6. The cell culture apparatus according to claim 5 , wherein the base is pivotably supported by a supporting frame such that the base can be rotatably moved, and due to the rotational operation of the base, the engagement of the hook is released.

7. The cell culture apparatus according to claim 1 , wherein two or more fixtures that fix the container are vertically provided such that they oppose each other on a periphery of the base, and a recess is formed in each of the two or more fixtures.

8. The cell culture apparatus according to claim 7 , wherein the recess is formed in each of the two or more fixtures at a position, upwardly from the surface of the base, corresponding to ½ to 3/2 of a thickness of the container when the container is filled to capacity.

9. The cell culture apparatus according to claim 7 , wherein the recess is formed in each of the two or more fixtures circumferentially relative to the horizontal plane.

10. The cell culture apparatus according to claim 7 , wherein each of the two or more fixtures is provided vertically at each of corners of the base.

11. The cell culture apparatus according to claim 7 , wherein two or more holes are provided at end parts of the container such that they correspond to any of the two or more fixtures, and any of the two or more fixtures are inserted into the holes to allow peripheral parts of the holes to be engaged with the recess.
