Therapeutic cloning involves using cloning processes to produce embryonic stem cells, tissues or whole organs for transplantation. The main ethical issues associated with therapeutic cloning are those relating to the creation and destruction of embryos, and whether refining the cloning technique will create a ‘slippery slope’ from therapeutic to reproductive cloning1. Reproductive cloning is the use of cloning to grow a living person who shares the DNA of the progenitor. Live animals have been cloned using fission (in the cattle industry) and SCNT (e.g. Dolly the sheep). There are currently no confirmed cases of deliberate cloning of a human embryo that was allowed to grow into a live baby. However, many countries (e.g. the UK, Australia)
