Therapeutic cloning ethics essay

Therapeutic cloning: Cloning designed as therapy for a disease. In therapeutic cloning, the nucleus of a cell, typically a skin cell, is inserted into a fertilized egg whose nucleus has been removed. The nucleated egg begins to divide repeatedly to form a blastocyst. Scientists then extract stem cells from the blastocyst and use them to grow cells that are a perfect genetic match for the patient. The cells created via therapeutic cloning can then be transplanted into the patient to treat a disease from which the patient suffers. In contrast to the goal of therapeutic cloning, the goal of reproductive cloning is to create a new individual, an idea that has stirred great controversy and met with almost uniform disapproval.

Artificial embryo splitting or embryo twinning , a technique that creates monozygotic twins from a single embryo, is not considered in the same fashion as other methods of cloning. During that procedure, a donor embryo is split in two distinct embryos, that can then be transferred via embryo transfer . It is optimally performed at the 6- to 8-cell stage, where it can be used as an expansion of IVF to increase the number of available embryos. [24] If both embryos are successful, it gives rise to monozygotic (identical) twins .
