Bioreactor for suspended cells

A bioreactor for suspended cells comprising:

• a housing formed in a box shape having a culture space with a predetermined volume and including a seeding port for seeding suspended cells into the culture space through a medium containing the suspended cells on one side;
• a support assembly formed of a plate-shaped member having a predetermined area and including a plurality of supports disposed in multiple stages at intervals along one direction of the housing;
• a gas inlet formed through the housing by a predetermined area to allow gas to flow into the culture space from the outside;
• and
• a porous member covering the gas inlet to allow the gas to enter the culture space from the outside while preventing the medium from leaking to the outside,
• wherein the culture space includes a medium storage space filled with a certain amount of medium so that all of the plurality of supports are submerged and a gas storage space located above the medium storage space and filled with gas, and
• the medium storage space includes a plurality of cell growth spaces separated from each other by the plurality of supports disposed in multiple stages at intervals.
