Cell culturing method using small-piece porous membrane |
| abstract |
The purpose of the present invention is to provide a cell culturing method using a small-piece polymer porous membrane. The present invention provides a cell culturing method which does not require stirring and comprises applying cells to a small-piece polymer porous membrane having an area of a surface layer A or B of at most 4 mm2, and culturing the cells. The small-piece polymer porous membrane has a characteristic three-dimensional structure, and a medium can be more easily supplied and recovered by utilizing the property that small-piece polymer porous membranes are dispersed in a cell culture solution and/or small-piece polymer porous membranes are accumulated in multiple layers, and thus the small-piece polymer porous membranes are dispersed and/or laminated on a bottom part of a cell culture vessel. Consequently, long-term culture and mass culture are achieved, and thus the stable long-term production of exosomes is possible. |
