Cell culture incubators with integrated cell manipulation systems
Aspects of the invention relate to automated cell culture incubators. In some embodiments, automated cell culture incubators comprise an integrated manipulation having one or more cell scrapers.
1. A cell culture incubator comprising:
an incubator cabinet comprising an internal chamber having a controlled temperature and gas mixture therein appropriate for the growth of a type of cell for incubation of said type of cell in one or more cell culture vessels in the internal chamber;
a door opening from an external environment to said internal chamber;
an imager disposed in the internal chamber and configured for imaging said type of cell within said internal chamber;
a manipulator disposed in the internal chamber and for manipulating said type of cell in said one or more cell culture vessels within said internal chamber; wherein the manipulator comprises one or more cell scrapers, wherein each cell scraper comprises a handle portion comprising an elongate member extending from a proximal region that is connectable to a manipulator base and a distal region that comprises a scraping edge, a channel extending from the proximal region to the distal region, and an opening at the scraping edge in communication with the channel for transporting at least one of cells or cell culture media with respect to the cell culture vessel; and
a cell culture vessel transfer device disposed in the internal chamber and for moving said one or more cell culture vessels between locations within said internal chamber.
2. The incubator of claim 1 , wherein said imager is a phase contrast imager.
3. The incubator of claim 1 , wherein said imager is a bright-field imager.
4. The incubator of claim 1 , wherein said imager is a fluorescence microscope imager.
5. The incubator of claim 1 , wherein said one or more cell culture vessels comprise fiducial marks for facilitating alignment of said one or more cell culture vessels to said imager and said manipulator.
6. The incubator of claim 1 , further comprising an imaging location, wherein the imaging location comprises fiducial marks.
7. The incubator of claim 1 , further comprising a controller to control said manipulator.
8. The incubator of claim 7 , wherein said controller is located exterior to said incubator cabinet.
9. The incubator of claim 8 , wherein said controller comprises a computer.
10. A cell culture incubator comprising:
an incubator cabinet comprising at least one internal chamber for incubation of a type of cell in one or more cell culture vessels and having a controlled temperature and gas mixture in the at least one internal chamber appropriate for the growth of the type of cell;
a door opening to said at least one internal chamber;
at least one imager disposed in the at least one internal chamber in at least one imaging location and configured for imaging said type of cell in said at least one cell culture vessel;
a manipulator disposed in the at least one internal chamber for manipulating said type of cell in said one or more cell culture vessels, wherein the manipulator comprises one or more cell scrapers, wherein each cell scraper comprises a handle portion comprising an elongate member extending from a proximal region that is connectable to a manipulator base and a distal region that comprises a scraping edge, a channel extending from the proximal region to the distal region, and an opening at the scraping edge in communication with the channel for transporting at least one of cells or cell culture media with respect to the cell culture vessel; and
a cell culture vessel transfer device disposed in the at least one internal chamber for moving said one or more cell culture vessels to and from said at least one imaging location.
11. The incubator of claim 1 , wherein each cell scraper comprises a handle having an interface for replaceably connecting a scraping edge assembly to the handle.
12. The incubator of claim 1 , wherein each cell scraper comprises a scraper edge contactable with the surface of a cell culture vessel and configured for scraping cells adhering to the surface without substantially killing the cells.
13. The incubator of claim 1 , further comprising a controller configured for controlling the manipulator to modulate the contact pressure between a scraping edge of the cell scraper and the surface of a cell culture vessel.
14. The incubator of claim 10 , wherein said at least one imager is a phase contrast imager.
15. The incubator of claim 10 , wherein a second imager is a bright-field imager or fluorescence imager.
16. The incubator of claim 1 , wherein each cell scraper comprises a contiguous structure comprising a scraping edge.
17. The incubator of claim 1 , wherein each cell scraper comprises interconnected parts.
18. The incubator of claim 1 , wherein each cell scraper comprises a handle having an interface for replaceably connecting a scraping edge assembly to the handle.
19. The incubator of claim 1 , wherein each cell scraper comprises a scraper edge contactable with the surface of a cell culture vessel and configured for scraping cells adhering to the surface without substantially killing the cells.
20. The incubator of claim 1 , further comprising a controller configured for controlling the manipulator to modulate the contact pressure between a scraping edge of the cell scraper and the surface of a cell culture vessel.
