摘要

Cell aggregate formation control and cell aggregate disintegration control are carried out with respect to cells in a culture container to increase cell proliferation efficiency. The number of the cells in the culture container is counted without disassembly of a culture system and irrespective of the density of the cells. An external force is applied to the culture container to carry out at least one of cell aggregate formation control and cell aggregate disintegration control with respect to cells in the culture container, thus culturing the cells. The external force is applied to the culture container by pressing an agitating member onto a top surface of the culture container placed in flat orientation to a predetermined pressing degree, and moving the agitating member in a horizontal direction at a predetermined speed, thus controlling at least one of cell aggregate formation and cell aggregate disintegration with respect to the cells in the culture container. A method for counting counted targets disposed in a liquid enclosed in a container includes adjusting a thickness of at least a part of the container. At least a part of the adjusted part is set as a measurement target region. A number of counted targets in the measurement target region is counted.
