Abstract
To engineer a stem cell genome, we developed a technology for targeted elimination of chromosomes from mouse embryonic stem (ES)–somatic hybrid cells. Here we demonstrate the use of a universal chromosome elimination cassette (CEC) for elimination of a single embryonic stem cell (ESC)-derived chromosome 11 or 12, and also both copies of chromosome 6, which harbor pluripotency-associated genes including Nanog. We attribute hybrid-cell pluripotency to the expression of Nanog from the reprogrammed somatic-cell nuclei.
