"Christopher Reeve: I work with Dr. John McDonald at Washington University in St. Louis, and he is a very knowledgeable researcher on (Inaudible) stem cells, and a few years ago he said to me that in order to cure my particular condition, which is demyelination of nerves in a very small area of the spinal cord, right at the second cervical vertebrae, that if you imagine the rubber coating around a wire that allows conductivity of electricity, the same thing as with nerves, myelin is like that rubber coating. It's a fatty substance that if it comes off of the nerves, then signals do not go from the brain down to the spinal cord as required. However, it is possible, and he's demonstrated this as graphic(?) as possible, to re-myelinate. Now, a few years ago, he said, we would be willing to inject human embryonic stem cells into you and hope for the best. But hoping for the best is a very dangerous proposition for people with spinal cord injuries because our spinal cord injury affects every organ in the body, and the most serious side effect is that it severely compromises the immune system, so spinal cords patients, particularly with high level injuries like mine, are prone first to pneumonia, which I've had at least five times since my injury, many patients often die from that. Also, it compromises the cardiovascular system, compromises the digestive tract, the ... your whole bowel-bladder-sexual function, skin integrity and also bone density, so that osteoporosis becomes a very ... a very critical factor. So literally he said to me that the immunosuppression that would be required just to inject 30million human embryonic stem cells from an anonymous donor might kill me. And now, he would be unwilling as a doctor, because of the ethics involved that a doctor is ethically bound to give his patients the best possible treatment, he would not inject me with embryonic stemcells unless we go the other route, which is therapeutic cloning- taking an egg, removing the nucleus, taking DNA from my skin and deriving stem cells from that, which would be injected in a manner that would probably not be rejected by my immune system. So my future, and others would agree, many scientists would agree, my future, in terms of being able to recover will depend on some way of delivering stem cells without compromising my immune system and therapeutic cloning, which would use my DNA is the best hope."
