Japanese researchers have been able to revert adult mouse stem cells into an embryonic-like state according to the online article from the journal, Cell. If this same technology can be used on adult stem cells we will be able to obtain all the benefits of embryonic stem cell research without the moral problems associated with it. Of course, should we be able to do so I can guarantee you biotech industries will still be pushing for cloning and the destruction of human embryos. See this article that explains why.
