Abstract: [PROBLEMS] Relating to a bioassay method with the use of cultured cells and cell culture for a therapeutic purpose in the case of determining the efficacy of a drug or the like or examining the toxicity thereof, it is intended to provide a method of culturing cells under regulation in the extension direction and a cell culture plate. [MEANS FOR SOLVING PROBLEMS] A cell culture plate having a plural number of side walls (1) and a plural number of space structures (3) for providing cultured cells which are formed by the side walls (1), wherein the side walls (1) are provided with openings (2) so that the space structures (3) are linked together. By using this cell culture plate, a method of culturing cells under regulation in the extension direction can be provided.
