LONDON: Scientists have for the first time turned adult human skin cells into stem cells, which can grow into any type of tissue in the body, using cloning techniques.
Using the cloning technique which produced Dolly the sheep in 1996, researchers were able to turn skin cells from a 35-year-old man and a 75-year-old man into stem cells, raising the prospect that body parts could be regenerated in old age.
Last year, a team of researchers had created stem cells from the skin cells of babies but it was unclear whether it would work in adults because cells mutate with age.
Cloning a Chow Chow will be easy and will also cost at least half of what it would cost to clone any other type of dog, announced a South Korean biotech company today while presenting new cloning technology.
But dog-owners – who pay 100,000 dollars or more to clone a pet – will still have to pay tens of thousands of dollars if they want to clone their beloved four-legged friends, and must be prepared for long waiting-lists, because most cloning at a commercial level involves dogs used for work, like police dogs used in airports.

One of the most prestigious prizes in medicine is being awarded this year to scientists working on stem cells and leukemia — and to New York‘s mayor for his fight to cut tobacco use (…)
The Lasker Basic Medical Research Award goes to John Gurdon, 76, of Cambridge University and Shinya Yamanaka, 47, of Kyoto University and San Francisco‘s Gladstone Institute of Cardiovascular Disease. Their work has helped pave the way for the possibility of made-to-order stem cell treatments for individual patients

Korean scientists are moving closer to cloning embryonic stem cells, the unprecedented breakthrough that their compatriot and disgraced scientist Hwang Woo-suk claimed to have achieved in 2004, only to have this disproved later.
Currently, a team at the Cha Medical Center is working on a project after getting state approval last year, while another team headed by professor Park Se-pill at Jeju National University is also set to begin research.
Park and his associates are awaiting final approval from the National Bioethics Committee.

After the decision of the United States to remove the ban preventing stem cell researchers from using public funding for experiments, legislators in South Korea have been put under pressure by scientists who have been aspiring to do experiments on stem cells from cloned human embryos.
Up until a few weeks ago the National Bioethics Committee continued to postpone a decision on the matter, but now thanks to the American president, it is increasingly probable that at most, by the end of April, researchers of the Cha Medical Institute of Seoul will be able to resume
