Method for producing reprogrammed cells using a non-chromosomal viral vector

摘要

An object of the present invention is to provide a vector for easily and efficiently producing ES-like cells in which a foreign gene is not integrated into a chromosome. The present inventors have found a method for producing ES-like cells from somatic cells using a non-chromosomal viral vector. Since the prepared ES-like cells do not have foreign genes integrated into their chromosomes, they are not only convenient for testing and research using these cells, but also in the treatment of diseases, the problem of immune rejection and ethical aspects. The problem may be avoided.
