    摘要: An object of the present invention is to provide a method for producing a reversibly immortalized cell which can allow a cell into which an immortalizing gene is introduced to proliferate over a long period without damaging the chromosome of the cell, and is capable of removing the immortalizing gene, and to provide a method for obtaining a large amount of a reversibly immortalized cell that can be cloned and has stable quality. The present invention provides a method for producing a reversibly immortalized cell, comprising the steps of introducing a chromosomally non-integrated RNA virus vector loaded with one or two or more immortalizing gene(s), selected from the group consisting of Bmi-1 gene, TERT gene, and SV40T gene, into a mammalian cell so that the immortalizing gene is expressed in the cell; and culturing the obtained cell for proliferation.
