Human heart can regrow muscle cells after a heart attack, says new research
In a world-first discovery, scientists in Australia have found that the human heart can regrow muscle cells after a heart attack, raising hopes for future regenerative treatments for heart failure, and subsequently overall health.
The study, published in Circulation Research, revealed that while parts of the heart remain scarred after a heart attack, new muscle cells are also produced, a phenomenon previously seen only in mice and now demonstrated in humans for the first time, Xinhua news agency reported.
"Until now we`ve thought that, because heart cells die after a heart attack, those areas of the heart were irreparably damaged, leaving the heart less able to pump blood to the body`s organs," said Robert Hume, research fellow at the University of Sydney and first author of the study.
