Describe the process used for harvesting embryonic stem cells

Altered Nuclear Transfer  New method

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,
