Advancements in science to create clone animals for commercial useProf. Park Se Pill of Jeju National University developed the quick freezing and thawing technology |
|
Korean scientists have succeeded in quickly freezing an egg that had been fertilized with a somatic cell and then being able to quickly thaw it when needed for the purposes of cloning. It is expected that this new development in cloning animals will be deployed on a commercial scale.
It was announced on June 13 at Jeju National University (JNU) that researchers including JNU Prof. Park Se Pill and those of Mirae Biotech. Co., LTD., had successfully cloned a Jeju black cow named ‘Heokusuni,’ from a breeding cow that had died three years prior with the use of this new technique.
Due to this advancement in technology, an egg fertilized through transplanting the nucleus of somatic cell, can be frozen rapidly at 196 degrees below zero and stored. After being quickly thawed, the cloned fertilized egg is transferred into the womb of a surrogate cow.
The team lead by Prof. Park had previously succeeded in cloning two Jeju black bulls name ‘Heokyeongdori’ and ‘Heokudori.’ However, they were created from freshly fertilized eggs. Before this new technology it was impossible to preserve a cloned fertilized egg. Prior to this advancement in technology it would take two to five hours to freeze with the use of expensive equipment, resulting in a low survival rate during the thawing process of 50 percent.
Prof. Park explained, “The newly developed technology made the cloning process simple by freezing the fertilized egg in 15 minutes and thawing it in one minute any time it is transplanted. Also, the survival rate is 80 to 90 percent.”
He also said, “This technology established the basis for real commercialization and industrialization of mass-productive cloning.” He added, “We plan to offer about 100 fertilized eggs that had already been created and saved, to the farms that want it.”
Prof. Park said, “Next year, we will obtain excellent results to cross the cloned black cow and black bull, to produce a new superior species.”
