Abstract

There is provided a system for cultivating cells in cell culture vessels. The system includes a liquid handling module, an incubator module, a testing module for performing measurement upon cells and/or media and generating output data, a manipulator module, and a workflow management module for controlling the execution of processes within the system. The workflow management module includes a smart decision making means for selectively processing cells and/or media in accordance with any of process definitions, operational rules and output data from the testing module. The workflow management module also includes manipulator control means and liquid handling control means for controlling the operation of the manipulator module and the liquid handling module respectively in accordance with any of the process definitions, operational rules and decisions from the decision making means.

Claims

1. A system for cultivating cells of a characteristic cell biology in a plurality of movable cell culture vessels, each vessel being suitable for containing cells in a culture medium, the system comprising:

a liquid handling module for processing liquid material;

an incubator module for maintaining the vessels in an environment suitable for cell culture;

a testing module for performing measurement upon cells and/or media and generating output data;

a manipulator module for conveying vessels between locations in the system; and

a workflow management module for controlling the execution of processes within the system, wherein the workflow management module includes;

decision making means for selectively processing cells and/or media in accordance with any of process definitions, operational rules and output data from the testing module;

manipulator control means which controls the operation of the manipulator module in accordance with any of the process definitions, operational rules and decisions from the decision making means; and

liquid handling control means for controlling handling operations in the liquid handling module in accordance with any of the process definitions, operational rules and decisions from the decision making means.

2. A system for cultivating cells as claimed in claim 1, wherein the workflow management module includes scheduling means for scheduling further processes in accordance with any of the process definitions, operational rules, output data from the testing module and decisions from the decision making means.

3. A system as claimed in claim 1, wherein the workflow management module includes means for modelling cell biology.

4. A system as claimed in claim 2, wherein the workflow management module includes:

means for examining the resulting schedule to determine system resource conflicts.

5. A system as claimed in claim 4, wherein the means for examining creates a requirement for labware and/or media.

6. A system as claimed in claim 4, wherein the workflow management module is arranged to predict shortfalls in appropriate labware and/or media.

7. A system as claimed in either of claim 4, wherein the workflow management module is arranged to predict shortfalls in system processing capacity.

8. A system as claimed in claim 7, wherein the system processing capacity is any of:

testing module measurement capacity, incubator capacity, liquid handling capacity, harvest capacity, lysis capacity, purification capacity, and centrifuge capacity

9. A system as claimed in claim 7, wherein the shortfall in system processing capacity is a shortfall in throughput and/or space.

10. A system as claimed in claim 4, wherein the means for examining includes means for resolving resource conflicts.

11. A system as claimed in claim 10, wherein the system further comprises a display means and wherein the means for resolving resource conflicts includes a user interface capable of receiving operator input in order to resolve resource conflicts and representing resource conflicts on the display means.

12. A system as claimed in claim 1, wherein the workflow management module includes incubator control means which controls the operation of the incubator module in accordance with any of the process definitions, operational rules, output data from the testing module and decisions from the decision making means.

13. A system as claimed in claim 1, wherein the control of liquid handling operations includes the control of the provision of liquid material delivered to or removed from a specific vessel.

14. A system as claimed in claim 1, wherein the liquid handling module includes a handling device for moving vessels between locations within a liquid handling area.

15. A system as claimed in claim 13, wherein the liquid handling module is capable of delivering controlled quantities of liquid material into a vessel, transferring controlled quantities of liquid material and/or removing controlled quantities of liquid material from the vessel.

16. A system as claimed in claim 14, wherein the liquid handling module is provided with a number of end effectors and is further arranged to pick up a selected one of the available end effectors.

17. A system as claimed in claim 16, wherein the liquid handling module is provided with a plurality of tip arrays, and wherein the liquid handling device is further arranged to pick up a selected one of the available plurality of tip arrays.

18. A system as claimed in claim 13, wherein the liquid handling module is provided with a means for piercing a closure.

19. A system as claimed in claim 13, wherein the vessel is provided with a lid and the liquid handling module is further arranged to engage, remove, and/or replace the lid.

20. A system as claimed in claim 1, further comprising an input/output module for output of vessels for further use, input of new vessels containing material for processing and/or for temporary storage of clean and used vessels.

21. A system as claimed in claim 1, wherein the system includes a plurality of cell culture vessels, each vessel being suitable for containing cells in a culture medium, the vessels being array vessels provided with a plurality of wells, each well being capable of containing a portion of liquid material in isolation from neighbouring wells.

22. A system as claimed in claim 21, wherein the system is capable of measuring and processing cell cultures in each well of the array vessels selectively and individually, in accordance with any of the process definitions, operational rules, output data from the testing module and decisions from the decision making means.

23. A system as claimed in claim 1, wherein the testing module includes an offline facility capable of receiving external data.

24. A system as claimed in claim 1, wherein the testing module includes an online testing apparatus for monitoring cell growth.

25. A system as claimed in claim 1, wherein an aseptic environment is maintained within one or more modules of the system.
