Instead, they want to use somatic cell nuclear transfer, the same process used to clone Dolly the sheep in 1997, to create embryonic stem cells.

FORBES: Cloning's High Cost

If I understand the tetraploid complementation technique utilized in these experiments correctly, then, scientists would no longer need to generate embryos via somatic cell nuclear transfer (cloning).

FORBES: The Line Between Embryonic And Pluripotent Stem Cell Research Is Blurring

The problem is that making them using somatic-cell nuclear transfer involves breaking up viable embryos, since the cells in question are found inside early-stage embryos, called blastocysts.
