Zebrafish is a small tropical fish found in Ganga, Hindus’ holy river. It is also widely found in aquariums these days. A zebrafish can repair up to 20 per cent of its heart muscle within weeks of it being lost.
Scientists believe that the zebrafish’s astonishing ability to regenerate its cardiac muscle might lead to the discovery of new drugs and treatments that will one day allow the human heart to heal itself after being damaged during a heart attack.
The research might one day lead to an alternative to the transplant operations that are the only hope for thousands of patients now.
