Abstract
Human induced pluripotent stem cells (iPSCs) are a promising source of cells for regenerative medicine, study of the pathogenesis of various diseases, screening of pharmacological drugs, and other clinical and basic research. However, the maintenance of the genetic stability of the cells during reprogramming, long-term culture, and directed differentiation is necessary for the use of iPSCs. Large chromosomal aberrations affect the quality of iPSCs most adversely, so the review focuses on the analysis of chromosomal abnormalities, including the recurrent aneuploidy; the sources of its origin, the effect of reprogramming, and long-term culture on the accumulation of chromosome aberrations are discussed. Cases of spontaneous correction of the iPSCs karyotype and the possibility of induced correction of the large chromosomal abnormalities by removing or silencing the extra homologue are considered.
