Australia Clones Pig

Australia has produced its first pig clone. The animal, which is now five weeks old, is said to be healthy and growing like any other pig.

The piglet was made using a brand new technology that could help prevent diseases of animals and supplement human organ transplants, the company behind the development claimed.

BresaGen Ltd, working with St Vincent's Hospital in Melbourne, said it produced the clone from cells that had been frozen in liquid nitrogen for more than two years.

The world's first pig clones were announced in March last year by researchers working for the Scottish biotechnology firm PPL Therapeutics. Last month, the commercial branch of the Roslin Institute said it had also managed to create gene-altered pig clones as well.
Modification of the animals' genetic make-up is vital if pig organs are to be used successfully in humans. Unaltered, animal livers, kidneys or hearts would be "refused" by the human immune system.



The first pig clones were born last year

BresaGen said the technology it used to clone Australia's pig was different from that used to make Dolly the sheep, the first large animal to be copied from an adult cell.

"Basically, what works in sheep doesn't work in pigs, so we had to start from scratch," said chief executive John Smeaton.

The company said its pig cloning technology, like that of PPL's, was potentially life-saving, with countless people around the world dying each year while they waited for organ transplants.

"It is anticipated that the new cloning technology will have a major impact in guarding against the outbreak of animal disease and in the area of xenotransplantation - the use of animal organs for transplantation into humans," the company said in a statement.
