- Human cloning technology could be used to reverse heart attacks. Scientists believe that they may 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.
- Cancer. We may learn how to switch cells on and off through cloning and thus be able to cure cancer. Scientists still do not know exactly how cells differentiate into specific kinds of tissue, nor to they understand why cancerous cells lose their differentiation. Cloning, at long last, may be the key to understanding differentiation and cancer.
- With the state of the science as it is at the moment it would involve hundreds of damaged pregnancies to achieve one single live cloned baby.
- What is more, all the evidence suggests that clones are unhealthy and often have a number of built-in genetic defects which lead to premature ageing and death. It would be completely wrong to bring a child into the world knowing that it was extremely likely to be affected by problems like these
Whatever your view, all the evidence is that a clone would not be identical to the original because it would have a different womb environment and would be brought up differently.
