Christopher Reeve on Cloning

“Why do we need therapeutic cloning? As a layman, several important reasons come to mind. One, implantation of human embryonic stem cells is not safe unless they contain the patient's own DNA. Two, efforts, to repair central nervous system disorders may need to recapitulate the process of fetal development, and that could only be accomplished by human embryonic stem cells. Three, therapeutic cloning is done without fertilizing an egg. It can be strictly regulated. If we also enforce an absolute ban on reproductive cloning, we will not slide down the dreaded slippery slope into moral and ethical chaos. Any powerful new technology comes with the possibility for abuse. But when we decide that the benefit to society is worth the risk, we take every possible precaution and go forward. The unfertilized eggs that will be used for nucleus transplantation will never leave the laboratory and will never be implanted in a womb. But if we do not make this research legal, if we do not use Government funding and oversight, it will happen privately, dangerous unregulated and uncontrolled.”

“In response to something that Dr. Frist said, I need to object, and that is that, Senator, you insist on separating therapeutic cloning and embryonic stem cells. However, in my own case, I require re-myelination of nerves. That means replacing the conductive coat of fat, myelin, that allows electricity to come down, currents from the brain to the central nervous system for function. At the moment, only embryonic stem cells have the potential to do that, and experiments are being done now in larger animals demonstrating that. In fact, a scientist at Washington University, Dr. John McDonald, whom I have been working with says that there is no way he would inject stem cells without being able to use my own DNA for safety reasons. So without the ability to use my own DNA, without that somatic cell transfer, I am out of luck. The other thing is to please remember that therapeutic cloning, nucleus transplantation, is done with unfertilized eggs. You keep referring to destroying an embryo. I think that destroying an embryo is what happens when the leftovers from fertility clinics are thrown out. We can agree that they go to the garbage routinely. But to say that an unfertilized egg has the same status, I believe is incorrect, and I think that this is the line of research that holds so much promise and can also get us around the ethical quandary that we keep putting ourselves in. We are talking about an unfertilized egg that will never leave the lab, that will never be implanted in a womb, and that can be regulated. And it is crucial for research.”
