What is therapeutic cloning?
Therapeutic cloning is the use of cloning technology in the search for new treatments and cures for diseases and disabilities. The genetic material or DNA is removed from an unfertilized egg and replaced with the genetic material of an adult somatic cell (e.g., skin cell). Stem cells that genetically match the adult somatic cell donor can be derived from this process. See graphic.
Once stem cells have been obtained, they can be induced to develop into specific types of cells or tissues. Since these specialized cells or tissues genetically match the adult somatic cell donor, they can be transplanted into the donor with little or no chance of the body rejecting them. Scientists also hope to use stem cells derived from therapeutic cloning to better understand how cells behave throughout their lifespan and how disease develops.
