Theories exist about how cloning may lead to a better treatment for heart attacks. Doctors will be able to treat heart attack victims by cloning their healthy heart 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 industrialized countries. If heart disease can be cured, then human life expectancy will increase. Although scientists do not know exactly how cells differentiate into specific kinds of tissue, nor understand why cancerous cells lose their differentiation, cloning, at long last, could answer how to switch cells on and off, thus curing cancer.
Cloning also has the power to cure infertility.
The current options for infertile couples are inefficient, painful, expensive, and heart breaking. Many couples run out of time and money without successfully having children. Sperm from the father could be transferred into the mother s egg, thus creating a unique child, not a clone. Because of cloning and its technology, organ transplants and cosmetic procedures, like silicone breast implants, that may cause immune disease should soon cease to exist. Victims of terrible accidents that deform the face and body should now be able to have their features repaired with new, safer technology.
