Producing embryonic stem cells using nuclear transfer is not the same as reproductive cloning
The use of nuclear transfer to develop disease-specific stem cells can be called research cloning, and the use of this technique for personalized tissue transplants is sometimes called therapeutic cloning. These terms must be carefully distinguished from reproductive cloning, in which the intent is to implant a cloned embryo in a female's womb and allow it to develop fully into an individual. This was the technique by which Dolly the sheep was made and is now widely used for reproductive cloning in animals, In humans, however, reproductive cloning has been actively discouraged by most in the scientific community.
