Disease-on-a-chip
The invention generally relates to a cell culture system for coculturing non-neoplastic and neoplastic cells on a planar member which more faithfully mimics the in vivo geometry of a lumen or a cavity.
1. A cell culture system comprising at least one monolayer of non-neoplastic cells supporting tumor nodules, wherein both the non-neoplastic cells and the tumor nodules mimic in vivo phenotype, comprising;
a planar member having at least one axis and thickness including at least one semicircular hemichannel extending in the direction of the at least one axis, the at least one semicircular hemichannel partially formed into the thickness of the member; and
a polymer layer in direct contact with the semicircular hemichannel to provide a substantially smooth surface, wherein the substantially smooth surface is configured to receive a plurality of cells.
2. The cell culture system of claim 1 , wherein the planar member comprises, acrylic, glass, plastic, or a combination thereof.
3. The cell culture system of claim 1 , wherein the plurality of cells are non-neoplastic cells.
4. The cell culture system of claim 1 , wherein the plurality of cells are non-neoplastic and neoplastic.
5. The system of claim 2 , wherein the non-neoplastic cells are arranged in a monolayer.
6. The cell culture system of claim 1 , wherein the polymer layer includes a cell attachment factor.
7. The cell culture system of claim 6 , wherein the cell attachment factor is laminin 111.
8. The cell culture system of claim 1 , wherein the at least one semicircular hemichannel has a width of between about 75 microns to about 120 microns.
9. The cell culture system of claim 1 , wherein the planar member further comprises domains.
10. The cell culture system of claim 9 , wherein the domains are separated by spacers.
11. The cell culture system of claim 10 , wherein the spacer comprises acrylic, glass, plastic, PDMS, or a combination thereof.
12. The cell culture system of claim 9 , wherein the planar member comprises up to 96 separate domains.
13. The cell culture system of claim 1 , wherein the length of the planar member is about 127 millimeters to about 128 millimeters.
14. The cell culture system of claim 1 , wherein the width of the planar member is about 85 millimeters to about 86 millimeters.
15. The cell culture system of claim 1 , wherein the at least one semicircular hemichannel does not traverse to the edge of the planar member.
16. The cell culture system of claim 1 , wherein the system is configured to interact with a cell culture robot.
17. A cell culture system comprising:
a planar acrylic member having at least one axis and thickness including at least one semicircular hemichannel extending in the direction of the at least one axis, wherein the planar acrylic member is configured to insert into a well plate, the at least one semicircular hemichannel partially formed into the thickness of the member; and
a polymer layer in direct contact with the semicircular hemichannel to provide a substantially smooth surface, wherein the substantially smooth surface is configured to receive a plurality of cells.
18. The cell culture system of claim 17 , wherein the planar acrylic member is up to 7000 microns in length.
19. The cell culture system of claim 17 , wherein the planar acrylic member includes up to 70 semicircular hemichannels.
20. The cell culture system of claim 17 wherein the cell culture system is configured to interact with a cell culture robot.
