NEW YORK (AP) - Scientists are reporting new progress in a method of creating stem cells without using embryos.
Experts say it's a more efficient way of reprogramming skin cells so they can turn into stem cells.
Embryonic stem cells, which have the ability to morph into any type of cell, continue to be controversial because embryos are destroyed.
One expert says the new approach in cell reprogramming might be
the first practical way to make stem cells to create new tissue for
conditions like diabetes and Parkinson's disease.
The reprogramming technique was first reported in 2007, and scientists have been working to fine-tune it. The new work was published online today by the journal Cell Stem Cell.
