A team of South Korean researchers have successfully cloned world's first transgenic dogs, which can produce a fluorescent protein that glows red under ultraviolet light.(sohu.com)

Even under natural light the red protein can be seen in the skin and fur.

Dogs share many common genetic diseases with humans and development of disease models using a transgenic approach has long been awaited. This new achievement may open the door for transgenic dog models of human disease.

"The next step for us is to generate a true disease model," team member Che Myong Ko was quoted by journal New Scientists as saying.

Byeong-Chun Lee and stem cell researcher Woo Suk Hwang were part of a team that created the first cloned dog, Snuppy, in 2005.Much of Hwang's work on human cells turned out to be fraudulent, but Snuppy was not, an investigation later concluded.
