WASHINGTON (Reuters) – Researchers who figured out how to make valued embryonic stem cells out of ordinary skin cells said on Friday they had found a way to cut one cancer-causing ingredient out of the mix.
But it came at a price — the method may be safer, but it is also less efficient.
Shinya Yamanaka of Kyoto University in Japan said the findings, published in the journal Nature Biotechnology, demonstrate that the stem cell breakthrough may have been exciting, but is nowhere near ready to be used in humans.
