The scientist who led the team that controversially created Dolly the sheep is abandoning the cloning of human embryos in stem cell research.
Professor Ian Wilmut, of Edinburgh University, believes a rival method developed in Japan holds the key to curing serious medical conditions.
The new method creates stem cells from fragments of skin and could remove the need to use human embryos.
Pro-life groups opposed to the use of embryonic cells have welcomed the move.
But Prof Wilmut said: "We've not made this decision because it's ethically better.
"To me it's always been ethically acceptable to think that if you could use cells from a human embryo to develop a treatment for a disease like motor neurone disease, for which there is no treatment at present, then that is an acceptable thing to do."
