Abstract: The present invention relates to a method for producing a cell mass structure, which produces a cell mass structure (adhesion pad 4) in which a plurality of cell aggregates 2 arranged inside a culture container 3 accommodating a culture liquid are fused to each other by being cultured. A plurality of pins 16 are erected inside the above-described culture container 3, the above-described cell aggregates 2 are accommodated by the plurality of pins 16 with parts between the plurality of pins 16 and pins 16 as accommodating portions H, and the cell aggregates 2 are cultured in a state of being accommodated in the plurality of adjacent accommodating portions H. It is possible to obtain a required shape and dimension, and the cell mass structure can be obtained without giving damage to cells further.

Abstract: An apparatus 1 for producing a cell mass sheet is structured so as to produce a cell mass sheet 4 in which a plurality of cell masses 2 that have been planarly arranged on a mounting surface 13a in a culture container 3 are fused to each other by being cultured. The apparatus includes guide means G that has a plurality of accommodating portions Ga which can accommodate the cell masses 2 therein, and suction nozzles 8 (supply means) that supply the cell masses 2 into the accommodating portions Ga of the guide means G, which are arranged on the mounting surface 13a; and is structured so that the suction nozzles 8 array the cell masses 2 on the mounting surface 13a, and after that, the guide means G retracts from the above the mounting surface 13a. The apparatus can produce a cell mass sheet that has a constant shape and also a uniform thickness.

Abstract: A device 2 for producing a three-dimensional structural body has an accommodating plate 3 in which an accommodating recess portion 3a for accommodating a cell mass 1 is formed, a support body 4 provided with a plurality of needle-shaped bodies 6 penetrating the cell mass, a suction nozzle 19 for adsorbing/holding the cell mass, and structure 20 for moving the suction nozzle.

Abstract: A device 2 for producing a three-dimensional structural body comprising an accommodating plate 3 in which an accommodating recess portion 3a for accommodating a cell mass 1 is formed, a support body 4 provided with a plurality of needle-shaped bodies 6 penetrating the cell mass, a suction nozzle 19 for adsorbing/holding the cell mass, and moving means 20 for moving the suction nozzle. The suction nozzle is provided with a tubular adsorbing portion 19a for adsorbing/holding one cell mass, and a diameter of the adsorbing portion is formed smaller than an outer diameter of the cell mass and larger than an outer peripheral diameter of a needle-shaped body 6a of the support body 4.
