  • Publication number: 20240076596
    Abstract: A cell culture container includes: an insert member having a membrane on which a cell is seeded, the insert member defining a first inner space that functions as an anaerobic chamber; a container having an attachment/detachment portion to and from which the insert member is attachable and detachable, the container defining a second inner space that functions as an aerobic chamber; a sealing member that closes an opening of the aerobic chamber between the attachment/detachment portion and the insert member with the insert member being attached to the attachment/detachment portion; and a transfer mechanism that transfers force to the sealing member. The sealing member closes the opening in response to an input of the force from the transfer mechanism.
