    Stem Cells

    In recent years, stem cells have been the subject of considerable excitement. Great progress has been made in understanding their mechanisms and unravelling their potential for therapeutic application. Widespread use of stem-cell-based therapies is still a long way off, but could one day benefit vast numbers of patients, including those with cancer, neurodegenerative disorders and heart disease.
