Abstract

A cell culturing system includes a docking station, a handling unit, a culturing module and an actuation layer. The culturing module has a culturing well and a culturing membrane separating the culturing well in an apical culturing chamber and a basal culturing chamber. The handling unit removably accommodates the culturing module and the actuation layer. The docking station has a coupling structure for removably holding the handling unit in a predefined position and an actuation feeding channel, wherein, when the handling unit is held by the coupling structure in the predefined position, a first end of the actuation feeding channel is connected to the actuation bore and a second end of the actuation feeding channel is connected to a connector.

Claims (30)

1. A cell culturing system comprising:

a docking station;

a handling unit;

a culturing module; and

an actuation layer,

wherein

the culturing module has a culturing well,

the handling unit has a seat for accommodating the culturing module and the actuation layer, and a bottom with an actuation bore associated to the culturing well, wherein the bottom is separated from the culturing module by the actuation layer, and

the docking station has a coupling structure for removably holding the handling unit in a predefined position and an actuation feeding channel, wherein, when the handling unit is held by the coupling structure in the predefined position, a first end of the actuation feeding channel is connected to the actuation bore and a second end of the actuation feeding channel is connected to a connector.

2. The cell culturing system according to claim 1 , wherein the culturing module has a culturing membrane separating the culturing well into an apical culturing chamber and a basal culturing chamber.

3. The cell culturing system according to claim 1 , wherein

the seat of the handling unit is arranged for removably accommodating the culturing module and the actuation layer; and

the actuation bore is associated to the culturing well and the bottom is separated from the culturing module by the actuation layer when the culturing module is arranged in the seat.

4. The cell culturing system according to claim 1 , wherein

the culturing module has an inlet well and an outlet well;

the bottom of the handling unit has an inlet bore and an outlet bore, wherein, when the culturing module is arranged in the seat, the inlet bore is associated to the inlet well and the outlet bore is associated to the outlet well; and

the docking station has an inlet feeding channel and an outlet feeding channel, wherein, when the handling unit is held by the coupling structure in the predefined position, a first end of the inlet feeding channel is connected to the inlet bore, a first end of the outlet feeding channel is connected to the outlet bore, and each second end of the inlet feeding channel and the outlet feeding channel is connected to a connector.

5. The cell culturing system according to claim 1 , comprising a pressure control unit connected to the actuation bore of the bottom of the handling unit, the pressure control unit having a pump arrangement, at least one port connected to the pump arrangement and a processor for controlling the pump arrangement, such that at each of the at least one port pressure is individually adjustable.

6. The cell culturing system according to claim 4 , wherein the cell culturing module has a cap arranged at a top of the culturing module in which the cap comprises a channel connected to the docking station via the culturing module and the handling unit and to the inlet well.

7. The cell culturing system according to claim 6 , wherein the cap of the cell culturing module has a second channel connected to the docking station via the culturing module and the handling unit and to the outlet well.

8. The cell culturing system according to claim 1 , wherein the cell culturing module comprises an actuation membrane arranged over the culturing well.

9. The cell culturing system according to claim 1 , wherein the cell culturing module has a first culturing well with a first cell type and a second culturing well with a second cell type that are connected to each other with a channel located between the handling unit and the culturing module.

10. The cell culturing system according to claim 9 , further comprising additional culturing wells that are interconnected.

11. The cell culturing system according to claim 2 , comprising a channel which connects two culturing wells at the apical side of the culturing membrane or at the basal side of the culturing membrane.

12. The cell culturing system according to claim 2 , wherein the culturing membrane comprises a mesh.

13. The cell culturing system according to claim 4 , comprising a channel having a valve, wherein the channel connects the outlet well and the inlet well.

14. The cell culturing system according to claim 1 , comprising a further docking station identical to the docking station, a cell culture hood and an incubation hood, wherein the docking station is arranged in the culture hood and the further docking station is arranged in the incubation hood.

15. The cell culturing system according to claim 1 , wherein the actuation bore of the bottom of the handling unit has a cavity section neighboring the actuation layer.

16. The cell culturing system according to claim 1 , comprising at least one further culturing module structurally identical to the culturing module, wherein the handling unit has at least one further seat for accommodating the further culturing module and the bottom of the handling unit includes at least one further actuation bore associated to a further culturing well of the further culturing module; and the docking station has a further actuation feeding channel, wherein, when the handling unit is held by the coupling structure in the predefined position, a first end of the further actuation feeding channel is connected to the further actuation bore and a second end of the further actuation feeding channel is connected to the connector.

17. The cell culturing system according to claim 16 , comprising at least one further actuation layer, wherein the further seat of the handling unit is arranged to accommodate the further actuation layer and the bottom is separated from the further culturing module by the further actuation layer.
