Luigi Vescovi (Top L), codirector of the San Raffaele Hospital's Stem Cell Research Institute in Milan, poses with scientists Giulio Cossu (Top R) and Rossella Galli in a Institute's laboratory September 19, 2000. [Scientist in Milan said they had shown that stem cells from the brains of adult rats can be used to generate muscular tissue in a discovery that could eventually have implications for transplant therapy. Vescovi said in a news conference that new research had proven what he called the transdifferentiation capacity of somatic adult stem cells. Its a process by which a cell from a given tissue can give rise to a cell form of a different tissue, possibly even of a different embryonic origin, he told Reuters after presenting a paper to be published in science journal Nature Neuroscience. ]
