WASHINGTON (AP) ? Scientists used a cloning technique to create the type of customized stem cells that show promise for treating disease. But the first-of-its-kind result comes with a big hitch.
The newly created cells have too much genetic material to function properly. They include DNA from two people, not just the patient the cells were meant to match. Scientists still have to figure a way around that before they can see if the cells can be turned into useful tissue for transplant to treat various diseases.
The research involved injecting DNA from skin cells of a volunteer into donor eggs. The research done at the New York Stem Cell Foundation is published online Wednesday in the journal Nature.
