摘要： 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.

摘要： An object of the present invention is to efficiently establish cells, tissues, and organs capable of serving as donors for treating diseases, without eliciting immune rejection reactions, without starting with an egg cell. This object was achieved by providing a pluripotent stem cell having a desired genome. The cell was produced by treating with a reprogramming agent, producing a fusion cell of an MHC deficient stem cell with a somatic cell, or after producing a fusion cell of a stem cell with a somatic cell, removing a gene derived from the stem cell by performing genetic manipulation with a retrovirus.

摘要： A gene is provided, which can be used as a marker for determining whether a certain cell, particularly an undifferentiated cell including a tissue stem cell, has pluripotency or an undifferentiated state. The gene is called Stm and includes a Stm1 gene, which is expressed specifically in a cell under an undifferentiated state if the cell has pluripotency. A kit for determining a differentiated state of a cell is also provided. The kit comprises (a) an agent capable of reacting specifically with a Stm gene or a Stm gene product; and (b) means for determining whether or not the Stm gene is expressed in the cell.

摘要： By exposing somatic cells to a component derived from ES cells to act on somatic cells and detecting the activity thereof, the reprogramming agent can be screened. Further, by exposing somatic cells to a component including a reprogramming agent or an isolated reprogramming agent, the somatic cells can be reprogrammed. Furthermore, according to the present invention, since the tetraploid cells have proliferating capability and pluripotency, such cells can be differentiated and the cells, tissues or organs, which can be used for transplantation, can be produced.
