Cloning to harvest embryonic stem cells

Cloned human embryos are stem cell breakthrough | New Scientist
"Scientists have demonstrated for the first time that therapeutic cloning in humans can be achieved.

The researchers in South Korea created 30 cloned embryos that grew to about 100 cells in size - further than any verified experiment so far. This meant they were able to harvest embryonic stem cells from one of the embryos. They further showed that the ESCs could develop into a variety of tissue types.

Their long-term hope is that such a procedure would provide a source of perfectly matched transplant tissue for the treatment of diseases such as diabetes and Parkinson's.

'In this precise moment there is a person in South Korea walking around with [embryonic] stem cells tailor-made for her,' says Jose Cibelli from Michigan State University. He is the only US researcher involved with the work, although not the cloning experiments themselves."
