The purpose of the present invention is to safely culture pluripotent stem cells that are capable of differentiating diversely without mutual cross-contamination. A main transport passage (31) is extended out from a stem cell adjustment area (20), which is provided with a processing chamber (21) for inducing pluripotent stem cells from somatic cells or egg cells or a processing chamber (21) for receiving and adjusting pluripotent stem cells induced at another facility. At least one branch transport passage (32) is branched off of the main transport passage (31) and a cell culturing area (40) comprising stem cell culturing chambers (41-44) and a cultured cell analysis chamber (45) therefor is disposed on each of the branch transport passages (32). Preferably, respective independent worker entrances (22, 47+48, 33) are provided for the stem cell adjustment area (20), the cell culturing area (40), and the transport area (30), and mutual entry and exit of workers between the areas (20, 40, 30) is prohibited.
