Unformatted text preview: re. Embryonic stem cells could then be 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.

UNCORRECTED PAGE PROOFS CELL DEATH AND CELL RENEWAL FIGURE 17.26 Therapeutic cloning In therapeutic cloning, the 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 genet...
