New research in mice indicates that a recently discovered type of stem
cell can help regenerate skeletal muscle that has been damaged by a genetic
disorder that causes muscular dystrophylike symptoms. The new work, by investigators
in Italy and the United States, was published on-line by the journal Science on July 10 (http://www.sciencemag.org/).
