    Abstract:
    The world's first cloned swamp buffalo (Bubalus bubalis) derived from adult ear skin fibroblast has been reported. Donor fibroblast cells were produced from biopsies taken from adult male ear skin and in vitro matured oocytes obtained from a slaughterhouse were used as cytoplasts. A total of 39 blastocysts and 19 morulae fresh embryos were transferred into 12 recipient buffaloes. Progesterone assays indicated establishment of pregnancy in 10 of the 12 buffaloes (83.3%) after 45 days, with six animals still pregnant at 3 months. One recipient maintained pregnancy to term and naturally delivered a 40 kg male calf after 326 days of gestation. DNA analysis showed that the cloned calf was genetically identical to the donor cells. Genotype analyses, using 12 buffalo microsatellite markers, confirmed that the cloned calf was derived from the donor cell lines. In conclusion, the present study reports, for the first time, the establishment of pregnancy and birth of the first cloned Thai swamp buffalo derived from adult ear skin fibroblast cells.
