In some countries, such as the UK, certain forms of gene editing research on human embryos are legal if the embryos are not implanted into a woman, and are destroyed after 14 days of development. (oxplore.org)
A vital question is whether we should allow this type of research - the editing of human embryos that will never be implanted into a woman, or indeed leave a petri-dish. (oxplore.org)
Importantly, therapeutic cloning research continued and ultimately contributed to the development of a new technology -induced pluripotent stem cell (iPS) technology-that holds out immense promise as a way of developing stem cell treatments that are 'customised' to an individual patient and can be created without the destruction of human embryos. (oxplore.org)
We propose that the parallel distinction should be drawn, and emphasised, in discussions of GE: we should distinguish between the gene editing of embryos for research purposes, and for reproductive purposes. (oxplore.org)
