Stem cell breakthrough ends ethical dilemma

Experts in Britain and Canada find way to make stem cells without destroying embryosScientists have found a way to make an almost limitless supply of stem cells that could safely be used in patients while avoiding the ethical dilemma of destroying embryos.In a breakthrough that could have huge implications, British and Canadian scientists have found a way of reprogramming skin cells taken from adults, effectively winding the clock back on the cells until they were in an embryonic form.The work has been hailed as a major step forward by scientists and welcomed by pro-life organisations, who called on researchers to halt other experiments which use stem cells collected from embryos made at IVF clinics.Sir Ian Wilmut, who led the team that cloned Dolly the Sheep and heads the MRC Centre for Regenerative Medicine at Edinburgh University where the work was done, said: "This is a significant step in the right...
