Frozen mice cloned - are woolly mammoths next?

WASHINGTON (Reuters) - Japanese scientists have cloned mice whose bodies were frozen for as long sixteen years and said on Monday it may be possible to use the technique to resurrect mammoths and other extinct species.
Mouse cloning expert Teruhiko Wakayama and colleagues at the Center for Developmental Biology, at Japan's RIKEN research institute in Yokohama, managed to clone the mice even though their cells had burst. 


They're calling it "biological alchemy": induced stem cells proliferate

CALL it biological alchemy: specialist pancreatic cells that secrete digestive enzymes have been converted directly into insulin-producing beta cells. Meanwhile, epithelial cells from the back of the eye have been coaxed into becoming a versatile, new type of stem cell.
Both advances, reported last week in Philadelphia, Pennsylvania, at the annual meeting of the International Society for Stem Cell Research (ISSCR), may take us closer to a "regenerative" approach to repairing damaged tissue 


Patent fight over dog cloning keeps disgraced scientist busy

It turns out that Woo Suk Hwang, formerly of Seoul National University before they booted him out for falsifying his research, is involved in a lawsuit with one of his former teammates, Byeong Chun Lee, or at least the preliminary pangs of a lawsuit.
Hwang is invovled with a U.S. company and Lee with a Korean one. The U.S. company has just told the Korean one to stop cloning dogs. In June, Lee's company managed to make four clones of a dog that can sniff out cancer in humans--so this technology does have more than sentimental application 
Learn Genetics from Sand Dollar

When predators are nearby, sand dollar larvae split--literally. The young marine invertebrates divide in half to become too small for hungry fish to detect. Researchers say this is the first time the strategy, known as cloning, has been documented as a form of defense. 


"Three-parent" technique: mitochondrial replacement could prevent muscular dystrophy and epilepsy
Darkfrog submitted, created time 9 months 2 weeks (news.nationalgeographic.com)
It sounds more impressive than it is -- they've replaced the mitochondria, not portions of the somatic DNA.
A team at Newcastle University has constructed ten embryos, presumably viable, that hold DNA from one man and two women. Doctors see this technique as a means by which parents carrying genetic diseases may have their own (mostly) genetic offspring without going all the way to sperm donors, egg donors or surrogates 


Human Embryos Cloned From Skin Cells

A new breakthrough on stem-cell research!
A major breakthrough occurred last year when scientists figured out how to turn skin cells into ES-like cells. But they still want to be able to do cloning, otherwise known as somatic cell nuclear transfer (SCNT), because embryonic cells are the "gold standard" for pluripotent cells--cells that can become any cell type in the body. In addition, scientists want to learn more about how an oocyte can reprogram a mature cell back into an ES cell. 


Food from cloned animals deemed safe in US

In a long-awaited decision, the US Food and Drug Administration (FDA) has announced that food from cloned animals and their offspring is safe for consumption. But the US Department of Agriculture (USDA) urged producers to preserve a voluntary moratorium on marketing food from cloned animals until regulators can determine how best to introduce them into the US meat and dairy market. 


Glowing Pig Passes Genes to Piglets

A cloned pig whose genes were altered to make it glow fluorescent green has passed on the trait to its young, a development that could lead to the future breeding of pigs for human transplant organs, a Chinese university reported.
Besides,Tokyo's Meiji University last year successfully cloned a transgenic pig that carries the genes for human diabetes, while South Korean scientists cloned cats that glow red when exposed to ultraviolet rays—an achievement they said could help develop cures for human genetic diseases 


Debate heats up over food from cloned animals

US Department of Agriculture should study the economic implications of allowing meat and milk from cloned animals into the food supply. Now public are debating whether food from cloned animals and their progeny should be allowed on the shelves of US grocery stores.
This just is a news, but different individual has different viewpoint about that. In the point of my view, I object to eating food from cloned animals because it's might dangerous. 


Disgraced cloner Woo Suk Hwang attempts a comeback
jane2007 submitted, created time 10 months 4 weeks (www.nature.com)
In January 2006, Woo Suk Hwang’s apparent breakthrough articles announcing the first cloned human embryonic stem cells were shown to be fabrications. It was the biggest scientific scandal in recent history, and one might have thought his scientific career was over.But on 17 December an official said that Hwang had applied for a new licence for this type of work. Work continues to be published under Hwang's name.The Korean science ministry is expected to make a decision on the application by April 2008.

World faces choice on human cloning: U.N. study

The world faces a stark choice between banning cloning of humans or preparing ways to protect them from potential abuse or discrimination, a U.N. study said on Sunday. 


Cloning of endangered mammalian species: any progress?
medal submitted, created time 1 year 6 months (www.sciencedirect.com)
"Attempts through somatic cell nuclear transfer to expand wild populations that have shrunk to critical numbers is a logical extension of the successful cloning of mammals. However, although the first mammal was cloned 10 years ago, nuclear reprogramming remains phenomenological, with abnormal gene expression and epigenetic deregulation being associated with the cloning process

'Ten years ago, the birth of Dolly the sheep sparked a media frenzy and a prolonged ethical debate. Today, the arguments have switched focus to stem cells, and the research itself is beginning to change tack.'
