dc.description.abstractThe objective of the present study was to investigate whether nuclear transfer of postmortem wolf somatic cells into enucleated dog oocytes, is a feasible method to produce a cloned wolf. In vivo-matured oocytes (from domestic dogs) were enucleated and fused with somatic cells derived from culture of tissue obtained from a male gray wolf 6 h after death. The reconstructed embryos were activated and transferred into the oviducts of naturally synchronous domestic bitches. Overall, 372 reconstructed embryos were transferred to 17 recipient dogs; four recipients (23.5%) were confirmed pregnant (ultrasonographically) 23-25 d after embryo transfer. One recipient spontaneously delivered two dead pups and three recipients delivered, by cesarean section, four cloned wolf pups, weighing 450, 190, 300, and 490 g, respectively. The pup that weighed 190 g died within 12 h after birth. The six cloned wolf pups were genetically identical to the donor wolf, and their mitochondrial DNA originated from the oocyte donors. The three live wolf pups had a normal wolf karyotype (78, XY), and the amount of telomeric DNA, assessed by quantitative fluorescence in situ hybridization, was similar to, or lower than, that of the nuclear donor. In conclusion, the present study demonstrated the successful cloning of an endangered male gray wolf via interspecies transfer of somatic cells, isolated postmortem from a wolf, and transferred into enucleated dog oocytes. Therefore, somatic cell nuclear transfer has potential for preservation of canine species in extreme situations, including sudden death. (c) 2008 Elsevier Inc. All rights reserved.-
