Abstract
A culture device includes: a culture vessel that contains an aggregate of cells and a culture medium; a suction tube that suctions the culture medium in the culture vessel; a suction unit that generates suction force in the suction tube; and a control unit that controls the suction unit based on an antagonistic suction flow velocity of the aggregate, which is a velocity at which sedimentation of the aggregate is antagonistic to floating of the aggregate due to the suction of the culture medium.
Claims10
A culture device, comprising:
- a culture vessel that contains one or more aggregates of cells and a culture medium;
- a suction tube that suctions a culture medium in the culture vessel;
- a suction unit that generates suction force in the suction tube;
- and
- a control unit that controls the suction unit based on an antagonistic suction flow velocity of an aggregate, which is a velocity at which sedimentation of the aggregate is antagonistic to floating of the aggregate due to the suction of the culture medium, wherein
- the control unit controls the suction unit so as to suction the culture medium at a flow velocity equal to or lower than the antagonistic suction flow velocity of at least one of the aggregates.
A culture method, comprising suctioning, from a culture vessel that contains one or more aggregates of cells and a culture medium, the culture medium at a flow velocity corresponding to an antagonistic suction flow velocity of an aggregate, which is a velocity at which sedimentation of the aggregate is antagonistic to floating of the aggregate due to the suction of the culture medium, wherein
- the suctioning the culture medium includes suctioning the culture medium at a flow velocity equal to or lower than the antagonistic suction flow velocity of at least one of the aggregates.
