Chromosome rearrangements, such as large deletions, inversions, or translocations, mediate migration of large DNA segments within or between chromosomes, which can have major effects on cellular genetic control. A method for chromosome manipulation would be very useful for studying the consequences of large-scale DNA rearrangements in mammalian cells or animals. With the use of the Cre-loxP recombination system of bacteriophage P1, we induced a site-specific translocation between the Dek gene on chromosome 13 and the Can gene on chromosome 2 in mouse embryonic stem cells. The estimated frequency of Cre-mediated translocation between the nonhomologous mouse chromosomes is approximately 1 in 1200-2400 embryonic stem cells expressing Cre recombinase. These results demonstrate the feasibility of site-specific recombination systems for chromosome manipulation in mammalian cells in vivo, breaking ground for chromosome engineering.
