<P> In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell . The technique consists of taking an enucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell . It is used in both therapeutic and reproductive cloning . Dolly the Sheep became famous for being the first successful case of the reproductive cloning of a mammal . "Therapeutic cloning" refers to the potential use of SCNT in regenerative medicine; this approach has been championed as an answer to the many issues concerning embryonic stem cells (ESC) and the destruction of viable embryos for medical use, though questions remain on how homologous the two cell types truly are . </P> <Table> <Tr> <Td> </Td> <Td> This section needs additional citations for verification .
