The unencumbered ability to turn adult cells into embryonic ones capable of morphing into virtually every kind of cell or tissue, described in two scientific journal articles released today, has been the ultimate goal of researchers for years. In theory, it would allow people to grow personalized replacement parts for their bodies from a few of their own skin cells, while giving researchers a uniquely powerful means of understanding and treating diseases.
