Although mice cloned by somatic-cell nuclear transfer appear relatively normal, the long-term consequences of cloning are now becoming apparent. In an Advanced Online Publication from Nature Genetics, Ogonuki et al. report that cloned mice die earlier than normal animals (Nat Gen 2002, DOI:10.1038/ng841).They followed 12 male mice cloned from immature Sertoli cells, together with genetically matched controls and mice generated by spermatid injection. The cloned mice grew normally, but they began
