Jose Cibelli: If we try hard enough, all species will be able to be cloned. Host: It's been nearly a decade, since scientists successfully cloned a sheep named Dolly, that event raised of course, some legal and ethical questions about how to use, this amazing discovery and even whether we should? They say everyone has a double somewhere. But imagine, an exact duplicate of you. Cloning is not as simple as scanning a copy. There's the science. Bernard Siegel: It's a significant medical breakthrough Host: The Ethics. Dr. David Stevens: I think all human cloning should be banned. Host: And the politics. Male Speaker: I think the government should take a law in this. Host: To understand the issue, we must first understand cloning. Bernard Siegel: Reproductive cloning is an attempt to actually clone a human being. Therapeutic cloning is a form of stem cell research where you would take a donor's body cell and place it into an unfertilized human egg and be able to secure from that embryonic stem cells. Host: Bernard Siegel heads the Genetic Policy Institute, an organization seeking to ban reproductive cloning. Bernard Siegel: It violets the Nuremberg code against human experimentation. Host: And promote therapeutic cloning. Bernard Siegel: Therapeutic cloning offers the hope of understanding, treatment and cures for millions and millions of people around the world. Host: Scientists say embryonic stem cell may help cure diseases like Alzheimer's, Parkinson's, Diabetes and Spinal Cord Injury. Kevin Hoagland: A fell the wrong way, and in an instant, I knew something was wrong. Host: When Kevin Hoagland was 18, a wrestling match with his brother changed life as he knew it. Kevin Hoagland: I couldn't move. Host: For 27years, Kevin has been waiting for science to move forward. Kevin Hoagland: My ultimate wish is that, whatever cure they find will, alleviate any of this paralysis from ever happening, or it does, it's real short time. Host: Researches at the Mayo Clinic are looking at stem cells as source for regenerating tissue damage by Heart attack. Jose Cibelli: Embryonic stem cells love to make different tissues, the love to differentiate into hard into new ones. You don't have to push them too hard and they differentiate into different tissue. Host: The time line to actual cures depends on many factors, not the least of which is funding. Mike Castle: I want to see, American Medical Research's resources put into this as soon as possible. Host: Delaware Congressman Mike Castle, has teamed with Republican and Democratic colleagues on legislation to widen stem cell research. Mike Castle: We haven't quite, I guess got unto the tilting point, where we've convinced the White House that, that's the way to go. But I will continue to try to do that. Host: In August of 2001, President Bush announced the government would not fund research on any stem cell lines created after that day. Mike Castle: We feel that the policy needs to be opened up. Host: New Jersey and California have dedicated State money to Research but Castle thinks Federal money and the National Institutes of Health are key. Mike Castle: If you have an NIH coordinating operation, I think that's better. Host: And castle sighs with the scientists who oppose reproductive cloning. Jose Cibelli: There's a very, very clear difference between therapeutic and reproductive cloning. Host: But not everyone agrees. Dr. David Stevens: There's no difference morally between the two, whether it's reproductive or therapeutic. You're creating a Human being and sacrificing it for scientific purposes. Host: Dr. David Stevens is Head of the Christian Medical Association, he backs the President's policy restricting stem cell research. Dr. David Stevens: We dare not go down the road, where we're going to sacrifice one human being for the benefit of another. Bernard Siegel: Cells in a dish, standing alone, can never on their own turn into a human being. Dr. David Stevens: It wou
