Unformatted text preview: The chimera proposal, a chimera being a creature born of at least two different species, might, in theory, allow scientists to test if human embryonic stem cells do indeed have the power to grow into every tissue type in the body. KHIMAIRA was a three headed, fire-breathing monster with the fore-parts of a lion, the hindquarters of a goat, and the tail of a serpent. What is a clone? • An individual or group of individuals created through asexual reproduction from the same original individual. – Genetically identical – Embryonic stem cells. • When cultured, will reproduce asexually-- thus are clones US House Votes to Ban Human Cloning The US House of Representatives overwhelmingly voted to ban all forms of human cloning on Thursday, February 20, roundly defeating a rival bill that would allow the use of cloning technology for medical research. The Human Cloning Prohibition Act of 2003, passed by a vote of 241 to 155 after several hours of debate. It would ban all human cloning, including cloning to create a pregnancy or for medical research. It also would make it a crime to "receive or import a cloned human embryo or any product derived from a cloned human embryo ," with fines of $1 million &10 yrs in prison. This last provision troubled opponents, who feared it could turn patients seeking treatments abroad that might result from embryonic stem cell research into criminals. Embryonic Stem Cells: from in vitro fertilization •Yes, can use existing embryonic stem cell lines • No, cannot create new embryonic stem cell lines Remarks by the President on Stem Cell Research August 9, 2001 Name # cell lines BresaGen, Inc., Athens, Georgia 4 CyThera, Inc., San Diego, California 9 Karolinska Institute, Stockholm, Sweden 5 Monash University, Melbourne, Australia 6 National Center for Biological Sciences, Bangalore, India 3 Reliance Life Sciences, Mumbai, India 7 Technion-Israel Institute of Technology, Haifa, Israel 4 University of California, San Francisco, California 2 Göteborg University, Göteborg, Sweden 19 Wisconsin Alumni Research Foundation, Madison, Wisconsin 5 There are three types of cloning • Therapeutic cloning • Embryo cloning • Adult DNA cloning Therapeutic cloning: This is a procedure that starts off like adult DNA cloning. However, the stem cells are removed from the pre-embryo with the intent of producing tissue or a whole organ for transplant back into the person who supplied the DNA. The goal of therapeutic cloning is to produce a healthy copy of a sick person's tissue or organ for transplant. This technique would be vastly superior to relying on organ transplants from other people. The supply would be unlimited, so there would be no waiting lists. The tissue or organ would have the sick person's original DNA; the patient would not have to take immunosuppressant drugs for the rest of their life, as is now required after transplants....
