Cloning is seen as a possible way to aid some people who have severe medical problems . One potential use of cloning technology would involve creating a human repair kit . In other words, scientists could clone our cells and fix mutated genes that cause diseases. In January 2001, the British government passed rules to allow cloning of human embryos to combat diseases such as Parkinson's and Alzheimer's. While it may take time for cloning to be fully accepted, therapeutic cloning will likely be the first step in that direction.
Therapeutic cloning is the process by which a person's DNA is used to grow an embryonic clone.
However, instead of inserting this embryo into a surrogate mother, its cells are used to grow stem cells . These stem cells can be used as a human repair kit. They can grow replacement organs, such as hearts , livers and skin. They can also be used to grow neurons to cure those who suffer from Alzheimer's, Parkinson's or Rett Syndrome. The DNA is then inserted into an enucleated donor egg.
