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. (wikipedia.org)
Development will ensue normally and after many mitotic divisions, the single cell forms a blastocyst (an early stage embryo with about 100 cells) with an identical genome to the original organism (i.e. a clone). (wikipedia.org)
Stem cells can then be obtained by the destruction of this clone embryo for use in therapeutic cloning or in the case of reproductive cloning the clone embryo is implanted into a host mother for further development and brought to term. (wikipedia.org)
The aim of carrying out this procedure is to obtain pluripotent cells from a cloned embryo. (wikipedia.org)
Embryonic stem cells are undifferentiated cells of an embryo. (wikipedia.org)
