cultured from the cloned embryo and used to generate appropriate types of
differentiated cells for transplantation therapy. The major advantage provided by therapeutic cloning is that the embryonic stem cells derived by
this procedure would be genetically identical to the recipient of the transplant, who was the donor of the adult somatic cell nucleus. This bypasses
the barrier of the immune system in rejecting the transplanted tissue.

nucleus of a patient’s cell would be transferred to an enucleated egg,
which would be cultured to an early embryo. Embryonic stem cells
would then be derived, differentiated into the desired cell type and
transplanted back into the patient. The transplanted cells would be
