the embryos are grown into cell clusters.
the inner mass of the embryo is rich in embryonic stem cells.
the inner mass is therefore harvested , and the embryo discarded.
somatic Cell Nuclear Transfer (SCNT)-Old method.
somatic cells are grown in the laboratory.
donor cells with the nucleus removed are provided.
the somatic cells nucleus are removed, and planted into the donor cells.
the donor cells undergo pseudo fertilization, and the embryo formed.
the inner mass cells is harvested for the embryonic cells with the death of embryo,
