Cloning publications over time and breed differences. (A) Mammal cloning as represented by the number of articles published per year. (B) Representation of the number of publications by species per year, upper left indicates the scale difference of small laboratory animals, mice and rats, when compared to the most published of the larger species. Dotted lines indicate the peak in cloning publication as well as the declining slope of the trend from that point. (C) Timeline of published cloned animals, by somatic cell nuclear transfer, it should be noted that the Macaque, although included, was cloned using fetal cells.
