 Cloning for research and therapy could potentially offer a solution to this problem. An embryo produced via SNCT using the patient’s somatic cell as a donor cell would be virtually genetically identical to the patient. Stem cells obtained from that embryo would thus also be genetically identical to the patient, as would be their derivatives, and would be less likely to be rejected after transplantation. Though therapies using embryonic stem cells from SCNT embryos are not yet on the horizon for humans, scientists have provided proof of concept for these therapies in the mouse.
