|1. (WO2017033898) CELL CULTURE DEVICE AND BIOLOGICAL SAMPLE PRODUCTION METHOD|
|Applicants:||ASAHI GLASS COMPANY, LIMITED
|Title:||CELL CULTURE DEVICE AND BIOLOGICAL SAMPLE PRODUCTION METHOD|
The purpose of the present invention is to provide: a cell culture device which is capable of causing cells of various types to be adsorbed on a vessel surface during culture to promote organization thereof, is capable of desorbing a resultant biological sample without impairing the original function of the cells, and is capable of inhibiting desorption of the cells during culture; and a biological sample production method. This cell culture device 1 is provided with: a transparent culture vessel 10 in which a culture solution is accommodated; a dielectric layer 12 formed at the side of the inner bottom surface 10a of the culture vessel 10 such that a first surface 12a is in contact with the culture solution; a first electrode 14 provided to a second surface 12b of the dielectric layer 12 at the opposite side to the first surface 12a; a second electrode 16 provided inside the culture vessel 10 and away from the dielectric layer 12; and a voltage application mechanism 18 which applies a voltage between the first electrode 14 and the second electrode 16. The surface potential of the first surface 12a of the dielectric layer 12 changes as a result of applying the voltage between the first electrode 14 and the second electrode 16.
