Research on somatic-cell nuclear transfer might yield numerous benefits. Studies of stem-cell differentiation could provide valuable information about the mechanism of ageing or the cause of cancer.

Stem cells derived from this technology might also be a rich source of material for transplantation if specific genes or sets of genes in these pluripotent stem cells could be activated and if, as has been described before, the cells could then be coaxed to differentiate.

This is not theoretical, because differentiated cell types (vascular endothelium, heart and skeletal muscle, and neurones) have already been obtained by culturing embryonic stem cells from mice. If this technology could be applied to human stem cells, the resulting products might revolutionise medical therapeutics.
