Using cloning we can create skin for burn victims, brain cells for the brain damaged, hearts, lungs, livers, and kidneys. The technology also could be used to reverse heart attacks. There has been a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs or tissues to repair or replace damaged ones. Also, scientists believe that they may be able to treat heart attack victims by cloning their healthy cells and injecting them into the areas of the heart that have been damaged.
Heart disease is the number one killer in the United States and several other industrial countries.
Similarly, islet cells could be created from the skin cells of a diabetic and returned to the patient's pancreas, where they would produce insulin. ES cells could be used to repair tissue damaged by hepatitis, and we could grow nerves or the spinal cord back again when they are injured for quadriplegics and perhaps cure genetic diseases. By combining this knowledge with human cloning technology, it may be possible to produce needed tissue for suffering people that will be free of rejection by their immune systems. We should furthermore be able to clone the bone marrow for children and adults suffering from leukemia, which would allow the patient to avoid the relatively crude radiation and chemotherapy treatments used today. In addition, we may learn how to switch cells on and off through cloning and thus be able to cure cancer and produce effective genetic therapy against cystic fibrosis.
