Nobel Prize Awarded for Cloning and Stem Cells
Futuristic, but no longer far-fetched, regenerative medicine was brought a step closer to reality, thanks to the discoveries of two scientists who, on Monday, were jointly awarded the esteemed Nobel Prize in Physiology or Medicine for their pioneering work in the fields of cloning and stem cells.
John B. Gurdon of the University of Cambridge in England was the first to clone an animal. In 1962, he produced living tadpoles from the adult cells of a frog by removing the DNA-containing cell nucleus from a mature intestinal cell and injecting it into the nucleus of a frog egg whose nucleus had previously been extracted.
IPS cells are not yet being used to repair or replace damaged tissues or organs, but they are already showing great promise for modeling disease and testing new treatments. And the hope is that one day soon this technology will be used to treat a range of health problems from diabetes and blindness to Parkinson's disease and infertility.
