Abstract: It is solved by the rod-shaped tubular cell structure maintaining support device for cultivating a tubular cell structure including a hollow portion inside for a predetermined period of time while maintaining the hollow portion, the tubular cell structure maintaining support device including an outer diameter insertable into the hollow portion of the cell structure, and when inserted into the hollow portion, capable of allowing the tubular cell structure maintaining support device to adhere to an inner surface of the cell structure, and a penetration conduit including openings at both ends of the tubular cell structure maintaining support device, and penetrating between the openings, wherein the tubular cell structure maintaining support device has an oxygen permeable structure from the penetration conduit to an outer surface of the tubular cell structure maintaining support device.
