  2. Quotes on Therapeutic Cloning "...[medical] methods that fail to respect the dignity and value of the person must always be avoided. I am thinking in particular of attempts at human cloning with a view to obtaining organs for transplants: these techniques, insofar as they involve the manipulation and destruction of human embryos, are not morally acceptable, even when their proposed goal is good in itself." ﾊPope John Paul II in an address before International Congress on Transplants on 2000-AUG-29 "Somatic cell nuclear transfer (more commonly called therapeutic cloning) is about saving and improving lives. It is fundamentally different from human reproductive cloning; it produces stem cells, not babies." U.S. Newswire

  3. Cloning in general Cloning is the process of creating genetically identical cells or organisms by using individual animals/plants. There are three main types of cloning: DNA cloning, reproductive cloning and therapeutic cloning. Cloned Sheep

  4. What is it? Therapeutic cloning (research cloning) is when stem cells are extracted to grow into a piece of human tissue which is encouraged to grow into a human organ for transplant.

  5. What are its uses? - It is used for medical purposes, such as creating organs to transplant into a patient in need of that organ. If replacement organs are available to the sick and dying people, countless numbers of lives could be saved. Therapeutic cloning is a fast and efficient way to ‘repair’ damaged organs. - Therapeutic cloning can be used to make insulin-secreting cells to cure for diabetes; nerve cells to cure stroke or Parkinson’s disease

  6. How is it done? DNA is extracted from a human’s cell. The DNA is inserted into a woman’s ovum and allowed to develop and produce stem cells. The stem cells are removed from the pre-embryo and are treated to grown inyo whatever organ is needed. Thus, the new organ is transplanted into the patient. Stem cells

  7. Possible Benifits -Cloned organs using therapeutic cloning is better than organs donated by another person: -No rejection of organ because the organ’s DNA would match the patient’s DNA -Patients do not need to wait for an organ donor to donate his/her organs -Brand new organs can work more efficiently than donated organs -Saving more lives, which otherwise would be lost due to the waiting for a transplant

  8. Potential Problems -There are still many deficiencies/ethical disputes in therapeutic cloning: -Since therapeutic cloning is still in its early stages of development stem cells sometimes become mutated, thus rejected by the recipient’s body. -The production of stem cells needs to become more efficient. So far we need 100 eggs to produce one usable stem cell line. -Many pro-life supporters believe that human comes into existence at conception. When the stem cells are extracted the embryo dies, therefore pro-life supporters believe that this is murder.
