Therapeutic cloning possesses enormous potential for revolutionizing medical and therapeutic techniques. (who.int)
This is therapeutic cloning. (who.int)
Since that time, the discussion has turned towards the possibilities of cloning human beings either for research ("therapeutic") or reproductive purposes, and even as a potential means for organ farming. (cbhd.org)
Though both seek a ban on what is being called 'reproductive' cloning--in which a clonal human embryo is implanted in a woman with the intent that a cloned human being will be born--they differ dramatically with respect to what is being termed 'therapeutic' cloning. (cbhd.org)
To achieve this end, we believe that a comprehensive ban prohibiting both 'reproductive' and 'therapeutic' cloning is needed. (cbhd.org)
I. The overwhelming consensus in this country that human reproductive cloning should not be permitted necessitates a ban on both reproductive and 'therapeutic' cloning. (cbhd.org)
4 While most U.S. citizens support a ban on the reproductive cloning of human beings, they may or may not support a ban on 'therapeutic' cloning. (cbhd.org)
Yet, to enact a ban on the former while simultaneously permitting the latter would almost certainly result in instances of both reproductive and 'therapeutic' cloning. (cbhd.org)
That is, if it were legal to create clonal embryos for 'therapeutic'--but not for reproductive--purposes, the demise of these embryos would be required in order to prevent the illegal practice of reproductive cloning from occurring. (cbhd.org)
Indeed, if clonal human embryos were created in the laboratory for 'therapeutic' purposes, the mandate that they not be implanted or otherwise allowed to progress toward birth would prove very difficult to defend. (cbhd.org)
4. The so-called "therapeutic cloning", which would be better called "research cloning" because we are still far from therapeutic applications, has been proposed in order to avert the potential immune rejection of embryonic stem cells derived from a donor other than the host. (lifeissues.net)
Moreover, a non-human primate model of cloning, which would be necessary in order to conduct experiments to establish safety before attempting therapeutic experiments in human beings, has yet to be developed. (lifeissues.net)
5. The health benefits of therapeutic cloning are hypothetical, in as much as the method itself remains mainly a hypothesis. (lifeissues.net)
Indeed, even putting aside fundamental ethical considerations other than the patient's expectations, the present state of "therapeutic cloning" precludes, now and in the near future, any clinical application. (lifeissues.net)
The National Academy of Sciences, while supporting (2001) such so-called therapeutic or research cloning, has opposed (2002) the cloning of humans for reproductive purposes, deeming it unsafe, but many ethicists, religious and political leaders, and others have called for banning human cloning for any purpose.

First, if a ban only on reproductive cloning were adopted, enforcement would require the legally mandated destruction of human embryos created via cloning. (cbhd.org)
The Holy See opposes the cloning of human embryos for the purpose of destroying them in order to harvest their stem cells, even for a noble purpose, because it is inconsistent with the ground and motive of human biomedical research, that is, respect for the dignity of human beings. (lifeissues.net)
8 Technical problems aside, the need to extract these cells from living human embryos raises ethical questions of the highest order. (lifeissues.net)
It has been well established that most of the non-human embryos produced through nuclear transfer cloning are abnormal, with a deficiency in several of the genes (imprinted and non imprinted) necessary to the development of the early embryo. (lifeissues.net)
From a biological standpoint, bringing cloned human embryos to birth would be dangerous for the human species. (lifeissues.net)
