[31], Hills et al. [29] and Wakayama and Yanagimachi [56] also reported that development rates of somatic cloned embryo remained similar regardless of donor age. However, Kato et al. [36] noted that clones derived from adult cells frequently aborted in the later stages of pregnancy, and calves developing to term showed a higher number of abnormalities than did those derived from newborn or fetal cells. Forsberg et al. [58] transferred a large number of cloned embryos in cattle. They also concluded that, in general, embryos cloned from fetal cells produced higher pregnancy and calving rates than those from adult cells.","tracks":[]}
