Scientists say they have found a new way to mend damage to the heart. When cells turn into fully-formed adult heart muscle they stop dividing, and cannot replace tissue damaged by disease or deformity. But a US team have found a way to coax the cells to start dividing again, raising hopes they could be used to regenerate healthy tissue. The study, carried out on mice and rats by Children's Hospital Boston, appears in the journal Cell. In theory, it could be used to treat heart attack patients. (source: news.bbc.co.uk)
