Abstract: An object of the present invention is to provide a method of producing an intestinal epithelial cell, which has a large number of cells per area and a high accuracy of kinetic prediction for a CYP3A4 substrate drug such as midazolam, by inducing the differentiation of a pluripotent stem cell, as well as the intestinal epithelial cell, a cell sheet, an evaluation method for a test substance, a screening kit for a test substance, and a cell preparation.

Abstract: An object of the present invention is to provide a transportation instrument and a transportation method that enable transportation by using a cell culture container as it is. Further, an object of the present invention is to provide a transportation instrument and a transportation method that enable supply of oxygen required for respiration of cells. Further, an object of the present invention is to provide a transportation instrument and a transportation method that enable suppression of migration of a culture medium into and out of cells caused by the influence of an increase in internal pressure with respect to the temperature during transportation.

Abstract: An object of the present invention is to provide a method for producing a pluripotent stem cell that can efficiently differentiate into a target differentiated cell. According to the present invention, a method for producing a cell is provided, the method including a first step of obtaining an undifferentiated cell which is obtained by introducing a reprogramming factor into a somatic cell and has a relatively low ability to differentiate into a specific differentiated cell; and a second step of treating the cell while maintaining an undifferentiated state of the cell to obtain a cell having a relatively high ability to differentiate into the specific differentiated cell.
