U.S. media say a South Korean company has successfully delivered what it says are the world's first commercially cloned dogs.

MSNBC news said Bernann McKinney received five puppies that were cloned from her beloved late pit bull, Booger.

The report said the puppies are the work of the Seoul-based biotech firm RNL Bio, an organization affiliated with the lab which produced the world's first cloned dog and is staffed with former associates of disgraced scientist Hwang Woo-suk.

RNL scientists turned skin cells taken from Booger before he died two years ago into embryos carried by two surrogate dogs for two months. The dogs then gave birth to the puppies last week.

The cloning service fee initially stood at 150-thousand dollars, but Korean scientists lowered the price to 50-thousand dollars.
