The Australian government has issued its first license for cloning human embryos to obtain embryonic stem cells. (bioedge.org)
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)

Some studies published by Advanced Cell Technology and others have been touted as showing benefits from stem cells harvested from cloned animal embryos - but in each case, the study had to achieve its therapeutic goal by implanting the embryo in an animal's uterus and growing it to the fetal stage, then killing the fetus for more developed fetal stem cells. (thenewatlantis.com)

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. (infoplease.com)
If it is to be used in research, it is generally called therapeutic cloning. (discovery.org)
An Australian ban on therapeutic cloning was lifted in December 2006 after a long debate in Federal parliament. (bioedge.org)
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)
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)
