Breaking species barriers by breeding mice in a dish

Chan, Frank
Max Planck Research Group Molecular and Genomic Basis of Adaptation
How species differ from each other is a key question in biology. But genetic mapping between species has been challenging, because hybrid crosses are typically sterile. Combining latest stem cell and genomic techniques, the research group has pioneered in vitro recombination to circumvent breeding and directly cause gene exchanges in cells. In this way they have mapped differences between mouse species within weeks and created mouse embryos carrying hybrid mosaic genomes. By circumventing species barriers that prevent interbreeding this work sheds light on the genetic basis of trait variation.
