Revolutionary research could render plans to clone human embryos redundant.The research from America and Japan claims to reprogramme human skin cells so they cannot be distinguished from embryonic stem cells.Dolly the Sheep scientist Professor Ian Wilmut has already announced his intention to adopt the technique and abandon work on therapeutic human cloning."We can now envisage a time when a simple approach can be used to produce stem cells that are able to form any tissue from a small sample taken from any of us. This will have enormous implications for research and perhaps one day for therapy," he said.Although still at an early stage, the technique holds out the promise of manufacturing stem cells which can be used to repair almost any part of the body without having to clone human embryos.The advance could be used to treat Parkinson's, Type 1 diabetes, and motor neurone disease.The process effectively sets the cells back on the starting line, causing them to regress to an immature state. From this point they can follow any number of developmental pathways.© Independent Television News Limited 2007. All rights reserved.
