Tasmanian Tiger, also called Bandicoot

In the Hollywood movie "Jurassic Park", the human use of genetic technology successful revival of the dinosaurs.

United States and Australia researchers 20, announced that their successful use of mouse embryonic "resurrection" Australia extinct animal bag Wolf's gene, causing people to revive extinct animals.

"Resurrection" gene

United States University of Texas and Australia Melbourne University research staff of the joint study group on specimens from bag Wolf to isolate genes after implantation mouse embryo research.

Bandicoot is also called the Tasmanian Tiger, native to Australia Tasmania, the back have similar patterns of a tiger. Wild Wolf hunt for man bag at the beginning of the 20th century. Finally a Bandicoot in 1936 deaths in Australia Hobart Zoo.

However, part of childhood and adult specimens tissues Bandicoot was saved. Researchers are from Melbourne Victoria museum specimens of Bandicoot out gene on extraction.

Research Group released a statement saying: "group from a hundred years of history, Bandicoot on isolated the gene specimens. The identification of the gene for bag Wolf did, implantation mouse embryo, study its functionality. ”

The results showed that the bag of gene Wolf "resurrection", successfully led the mouse embryos out of the cartilage.

Significant

Research group leader, Melbourne University's Andrew · Pascal said: "the use of an extinct species of genes in other living organisms cause functional response, this is the first time. ”

Texas University's Richard · BEHRINGER said: "this research in many areas has huge potential significance, including the development of new types of biological medicinal products, as well as a better understanding of extinct animals. ”

Melbourne University, another researcher Marilyn · Len Foley said, when the increasing rate of animal extinction, the results of this study is extremely important.

Pascal in a telephone interview with Agence France-Presse said: "we have created a technology, human beings can use it to study any extinct species of gene function. Therefore, if there is a well-preserved gene, you can use this technique used in mammoth, burrowing mankind even dinosaurs. ”

Dead animals?

Mike · Archer is Australia New South Wales, University of the Academy. He served as the Museum of the long time Australia has tried to "clone" bag the Wolf. He said that the results of this study is "towards the direction marked an important step."

Pascal said that mankind in the future may be recycled extinct animals, but the current technology does not do this. "We can study an animal of a gene," he said, "but most of the animal has about 3 000 genes. ”

Pascal said: "We hope that with the advances in technology can achieve someday (Resurrection of extinct animals). Unfortunately, today we also do this. ”

Len Foley says that the purpose of this study is not a resurrection extinction animals. "Maybe one day all this will happen, but not in my lifetime," she said, "maybe in the future my children to see. But before carrying out this work, there are many way to go. ”
