First endangered black-footed ferrets, Mustela nigripes, cloned for genetic rescue

An endangered black-footed ferret female that died in 1988 with no living descendants in the current population was successfully cloned from cryopreserved cells using cross-species somatic cell nuclear transfer, producing three healthy kits. Incorporating progeny from these clones would provide an 8th founder to the breeding program and increase genetic variation to the species limited gene-pool. This marks the first time a native U.S. endangered species has been cloned.

Endangered Przewalski's horse, Equus pzrewalskii, cloned from historically cryopreserved cells

Two endangered Przewalskis horse stallions were cloned from fibroblast cells cultured and cryopreserved in 1980. These stallions are clones of a male that lived from 1975-1998 that pedigree analyses identified as a genetically valuable male for present-day conservation breeding. This is the first time that multiple healthy clones have been produced for an endangered species.
