SEOUL -- A pioneering South Korean stem-cell scientist said on Monday that his work met strict government guidelines on ethics, including on human egg donations, after a top U.S. scientist suspended collaboration. Professor Woo-Suk Hwang of Seoul National University did not comment directly on the move by Gerald Schatten of the University of Pittsburgh to halt his work with Hwang, citing possible irregularities recruiting egg donors. "We are the only research team (in South Korea) with the...

Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells. The fusion causes the adult cells to undergo genetic reprogramming, which results in cells that have the developmental characteristics of human embryonic stem cells. This approach could become an alternative to somatic cell nuclear transfer (SCNT), a method that is currently used to produce human stem cells. SCNT involves transferring the nuclei of adult...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Scientists have created a new human embryonic stem cell from an ordinary skin cell, U.S. researchers said on Monday. They hope their method, which fuses an embryonic stem cell to an ordinary skin cell and bone cells, could someday provide tailor-made medical treatments without having to start from scratch using cloning technology. That would also mean generating the valuable cells without using a human egg, and without...

by Jon Herskovitz SEOUL (Reuters) - Man can now reproduce his best friend -- South Korean scientists announced on Wednesday they had created the world's first cloned dog. Woo-Suk Hwang and his team of researchers at Seoul National University made world headlines earlier this year when they created stem cells with a patient's specific genetic material, derived through cloned embryos. Now they have cemented their place as leaders in the field by creating Snuppy, the first dog cloned from...

South Korea's pioneering stem cell scientist has cloned a dog, smashing another biological barrier and reigniting a fierce ethical debate - while producing a perky, lovable puppy. The researchers, led by Hwang Woo-suk, insist they cloned an Afghan hound, a resplendent supermodel in a world of mutts, only to help investigate human disease, including the possibility of cloning stem cells for treatment purposes. But others immediately renewed calls for a global ban on human reproductive...

Copenhagen, Denmark: Scientists in Belgium have discovered how to clone human embryos from eggs that have been matured in the laboratory. Their discovery should make it easier for scientists to create embryonic stem cell lines from cloned embryos and develop them to provide eggs and sperm for infertile couples, the 21st annual conference of the European Society of Human Reproduction and Embryology heard today (Monday 20 June). Until now, scientists investigating human cloning for therapeutic...

With the advent of nuclear-transfer cloning, it is now possible to produce mice from the nuclei of differentiated cells, such as peripheral blood lymphocytes and olfactory sensory neurons. However, unlike most other clones, those formed with the nuclei of differentiated cells were generated by a two-step nuclear-transfer procedure that might allow the donor genome further reprogramming. Thus, these findings do not settle the question of whether the egg cytoplasm can itself reprogram a fully...
