It is intended to provide a regenerable cell in which a desired chromosome has been deleted, a method for producing the cell, and a gene cassette and a kit to be used for the method. More particularly, it is intended to obtain an individual corresponding pluripotent stem cell easily and simply. More specifically, it is intended to efficiently establish a cell, tissue or organ that can be a donor for treating a disease without causing immune rejection response, without newly obtaining and establishing a stem cell such as ES cell from the individual, and without using an ovum as a material. It was achieved by a gene cassette in which not two recombinase recognition sites in a cis orientation are inserted, but one recombinase recognition site or two recombinase recognition sites in an opposite orientation is/are inserted and a marker gene is connected, and by application of the gene cassette to a cell fusion technique.
本发明旨在提供一种已删除所需染色体的可再生细胞、一种生产该细胞的方法,以及用于该方法的基因盒和试剂盒。更具体地说,本发明旨在简便易行地获得相应的多能干细胞个体。更具体地说,它旨在有效地建立一种细胞、组织或器官,这种细胞、组织或器官可作为治疗疾病的供体,而不会引起免疫排斥反应,无需从个体中重新获得和建立干细胞(如 ES 细胞),也无需使用卵子作为材料。它是通过一种基因盒实现的,这种基因盒不是插入两个顺式方向的重组酶识别位点,而是插入一个重组酶识别位点或两个反式方向的重组酶识别位点,并连接一个标记基因,以及将该基因盒应用于细胞融合技术。
