Research on cloning animals, again, came to the forefront of public attention in 1997. Most scientists involved in biomedical and agricultural research have emphasized the benefits, of which there are many, of cloning to the public. Basic studies on nuclear transfer have and will continue to contribute to our understanding of how genomic activation and cell cycle synchrony affect nuclear reprogramming and cloning efficiencies, specifically. Also, more basic information on actual mechanisms and specific factors in the oocyte causing nuclear reprogramming is forthcoming. As new molecular approaches in functional genomics are combined with nuclear transfer experiments, new genes involved in nuclear reprogramming will be found. The commercial potentials of products stemming from discoveries in cloning are vast. Cloning will be a more efficient, faster and more useful way of making transgenic fetuses for cell therapies, adult animals for protein production and organs for xenotransplantation. Clearly there are new opportunities in animal cloning technology that will produce many benefits to society.
