N/A - Experts support human cloning lyrics

Wednesday, 16 August, 2000, 16:21 GMT 17:21 UK Experts support human cloning Stem cell Geron Huge potential: An embryonic stem cell UK scientists should be allowed to carry out a limited form of human cloning, an expert panel told the British Government on Wednesday. Stem cells have major, major medical potential Prof Liam Donaldson A final decision on the issue will be left to a free vote of MPs, but ministers have endorsed the recommendations put forward by the Chief Medical Officer (CMO) in England, Professor Liam Donaldson, and his advisory group. Researchers believe they can revolutionise medicine if they are allowed to apply to humans some of the technology pioneered in Dolly the sheep. However, so-called therapeutic cloning, which could result in cures for diseases like Parkinson's and Alzheimer's, is highly controversial as it requires experiments on early-stage embryos. Close monitoring Professor Donaldson and his advisory group have been examining the issues surrounding therapeutic cloning for almost a year. Donaldson BBC Professor Donaldson's panel looked at the issues for almost a year They told the government that the technology was worthy of investigation but should be carefully controlled. Professor Donaldson said: "The committee looked very carefully at the ethical issues and decided the potential benefits outweighed some of the concerns and would be justified by the potential benefits for future generations of patients." The panel recommended that: Approval be given for the use of early embryos to investigate the potential of new medical treatments All research proposals be scrutinised by the Human Fertilisation and Embryology Authority Permission is only granted where it can be shown there are no other ways of meeting an experiment's objectives Any research should be constantly monitored, both by the authority and the newly created Human Genetics Commission Some of the steps in cloning should be used to help women who are at risk of pa**ing on certain rare disorders (mitochondrial diseases) because of problems with their eggs No cloning technology should be permitted where cell materials of humans and other animals are mixed Cloning for the purpose of making a baby (so-called reproductive cloning) should remain illegal Perfect-match tissue Central to therapeutic cloning are the "master" cells that exist in a human embryo when it is just a few days old. What is being proposed here is that we deliberately create and then deliberately destroy tiny human lives Peter Garrett, Life These embryonic stem (ES) cells are capable of developing into almost any kind of tissue in the body, including nerves, muscle, blood and bone. If these cells can be directed in the lab to become selected types of tissue, they could be used to treat a host of degenerative diseases which at present are incurable. And producing the embryos through a cloning step similar to the one used to make Dolly would ensure the transplant tissue suffered no rejection problems - it would be a perfect match for the patient. Although exciting developments are also being made with many other types of stem cell that are extractable from adults, many scientists believe only the ES cells will offer the full range of benefits they seek. Ethical objections Professor Ian Wilmut, the scientist who led the team that developed the cloning technology used to create Dolly, said: "In the end, this research to produce stem cells for therapy will lead to novel treatments for some conditions - such as Parkinson's disease, spinal cord injury, stroke and diabetes - that reflect damage to cells that aren't repaired or replaced. Mouse blastocyst BBC A blastocyst: ES cells are "harvested" from an early-stage embryo "There isn't an effective treatment for any of these conditions at the present time." However, "pro-life" groups and some churches denounced the panel's recommendations, arguing that therapeutic cloning was totally unacceptable - whatever the potential benefits. They said experimentation on embryos was an affront to the sanctity of human life. Peter Garrett, of Life, said: "What is being proposed here is that we deliberately create and then deliberately destroy tiny human lives. That's bad medicine and we should move away from it." Opponents also believe the acceptance of therapeutic cloning sets a dangerous precedent that will inevitably lead to so-called reproductive cloning - the creation of identical babies.
