Popis: Heteroplasmic mice represent a valuable tool to study the segregation of different mtDNA haplotypes (mtDNAs with differing alleles) in vivo against a defined nuclear background. We describe two methods for the creation of such models, differing in the resulting initial heteroplasmy levels: (a) transfer of ooplasm and (b) fusion of two blastomeres. These methods result in typical heteroplasmy of 5% and 50% donor mtDNA , respectively. The choice of method depends on the aim of the study. By means of breeding even 100% donor mtDNA can be reached within a few generations.
