From passion to progress People could have their own personal stem cells stored in readiness for when they might be needed.
Therapeutic cloning means killing.
At the heart of the therapeutic cloning controversy is a row over the removal of stem cells from embryos less than 14 days old. Stem cells are the parent cells of all the body's cells before they develop into specific types of cells such as blood cells, nerve cells or muscle cells. Benefits of therapeutic cloning Therapeutic cloning has the potential to benefit vast numbers of people. Embryonic stem cells can develop into any kind of tissue in the body, including nerves, muscle, organs and bone, depending on which chemical signals they are given. The procedure involves taking genetic material, creating an embryo out of it and then using the embryo's cells to form new tissues which would be identical to the patient's own tissues.
