Abstract

See full text

Means which enables preparation of a thick cell aggregate by a simple process without an operation of detaching and stacking of cells is disclosed. The method for preparing a three-dimensional cell aggregate by the present invention comprises: a cell encasing step of placing a cell suspension in a cell container; and a pressure application step of applying pressure to cells in the container. The cell encasing step and the pressure application step may be carried out a plurality of times. By the present invention, a thick, robust cell aggregate can be obtained by a simple operation of applying pressure to a cell suspension or a medium containing cells. Since the method does not require an operation of stacking a plurality of cell sheets, the cells are hardly damaged, and the conditions of the cells can be favorably maintained, so that the cells can be advantageously used as a tissue piece for transplantation.
