Abstract

A cell culture device includes: a stage on which a culture vessel is arranged, the culture vessel being a vessel for culturing a second cell generated from a first cell; and an oscillation mechanism that oscillates the stage.

First claim

1 . A cell culture device comprising:
a stage on which a culture vessel is arranged, the culture vessel being a vessel in which a second cell generated from a first cell is cultured; and an oscillation mechanism that oscillates the stage.

2 . The cell culture device according to claim 1 , comprising:
a magnet, wherein the magnet applies a magnetic load to the culture vessel to attract the first cell, the culture vessel holding a liquid that includes the first cell to which a magnetic particle is attached.

3 . The cell culture device according to claim 2 , wherein
in the attracting of the first cell, the stage is tilted with respect to a horizontal direction.

4 . The cell culture device according to claim 3 , wherein
while the first cell is being attracted, the oscillation mechanism oscillates the stage in an angular range smaller than an angle at which the stage is tilted with respect to the horizontal direction.

5 . The cell culture device according to claim 3 , wherein
in the culturing of the second cell in the culture vessel, the oscillation mechanism oscillates the stage in an angular range smaller than an angle at which the stage is tilted with respect to the horizontal direction.

6 . The cell culture device according to claim 1 , wherein
in the culturing of the second cell in the culture vessel, the culture vessel is tilted and a tilt of the culture vessel is gradually reduced.

7 . The cell culture device according to claim 6 , comprising:
a weight sensor that detects a weight of the culture vessel, wherein the tilt of the culture vessel is controlled in accordance with a weight of a liquid in the culture vessel, the weight of the liquid having been detected using the weight sensor.

8 . The cell culture device according to claim 1 , wherein
a culture medium and a liquid that includes the first cell are supplied to the culture vessel, the culture medium being for culturing the second cell.

9 . The cell culture device according to claim 8 , wherein
a supply path and a discharge path are connected to the culture vessel, the supply path being for supplying the culture medium or the liquid that includes the first cell, or both to the culture vessel, the discharge path being for discharging vessel liquid present in the culture vessel.

10 . The cell culture device according to claim 9 , wherein
the liquid that includes the first cell is supplied to the culture vessel from a cell vessel, the culture medium is supplied to the culture vessel from a culture medium vessel, and the cell vessel, the culture medium vessel, and the culture vessel define a closed space when the cell vessel and the culture medium vessel are each connected to the supply path and the discharge path.

11 . The cell culture device according to claim 9 , wherein
an oscillation fulcrum at which the stage is oscillated by the oscillation mechanism is positioned closer to, among the supply path and the discharge path, a path that has more routes.

12 . The cell culture device according to claim 9 , wherein
the supply path and the discharge path are connected to each other via a connection path, the cell culture device comprises a pump for circulating the culture medium by causing the culture medium in the culture vessel to pass through the discharge path, the connection path, and the supply path and return to the culture vessel, and the pump circulates the culture medium while the stage on which the culture vessel is arranged is tilted.

13 . The cell culture device according to claim 1 , comprising:
a temperature sensor provided to the stage, wherein in a top view, the temperature sensor is positioned on a side of the stage that is lower when the stage is tilted.

14 . The cell culture device according to claim 1 , wherein
a liquid including a viral vector is supplied to the culture vessel to infect the first cell with a virus to generate the second cell.

15 . The cell culture device according to claim 1 , wherein
the first cell is a hematopoietic stem cell, a liquid that includes the first cell is blood, and the second cell is an induced pluripotent stem (IPS) cell.

16 . A culture vessel arranged in the cell culture device according to claim 1 .

17 . The culture vessel according to claim 16 , comprising:
a supply port through which a culture medium and a liquid that includes the first cell are supplied to the culture vessel, the culture medium being from a culture medium vessel, the liquid that includes the first cell being from a cell vessel; and a discharge port through which vessel liquid present in the culture vessel is discharged, wherein the supply port and the discharge port are provided separately from each other.

18 . The culture vessel according to claim 17 , wherein
the cell vessel, the culture medium vessel, and the culture vessel define a closed space when the cell vessel and the culture medium vessel are connected to the supply port.

19 . The culture vessel according to claim 17 , wherein
in a top view, a shape of the culture vessel includes two short sides that oppose each other in one direction, and two long sides that oppose each other in an other direction that intersects the one direction, the culture vessel includes: a first supply port and a second supply port that are each the supply port; and a first discharge port and a second discharge port that are each the discharge port, the first supply port is provided to one of the two short sides of the culture vessel, the first discharge port is provided to an other of the two short sides of the culture vessel, and the second supply port and the second discharge port are provided to the other of the two short sides of the culture vessel, or are separately provided to one side and an other side, respectively, of the two long sides of the culture vessel.

20 . The culture vessel according to claim 17 , wherein
a supply path is connected to the supply port, the supply path being for supplying, to the culture vessel, the culture medium and the liquid that includes the first cell, a discharge path is connected to the discharge port, the discharge path being for discharging the vessel liquid present in the culture vessel, and the supply path and the discharge path are provided separately from each other.

21 . The culture vessel according to claim 20 , wherein
a cross-sectional area of a flow path of the supply path and a cross-sectional area of a flow path of the discharge path are different from each other.

22 . The culture vessel according to claim 20 , wherein
a filter that traps the second cell is provided to the discharge path, the second cell being included in the culture medium discharged from the culture vessel, the supply path includes a culture medium supply path through which the culture medium is supplied to the culture vessel, and the culture medium is supplied to the culture medium supply path to cause the second cell trapped by the filter to return to the culture vessel.
