Pill to Mend a Broken Heart 'Developed by Scientists' - University College London Study

British-based researchers claim they may be just a decade away from perfecting a way to persuade the heart to rejuvenate – a process thought to be impossible just five years ago. That means that when a heart attack occurs, the muscles and blood vessels around the organ could rebuild themselves – massively reducing long term damage and improving the quality of life of the victim. The researchers at University College London have discovered that a protein known as thymosin Beta 4, key to heart growth in the young, appears to reawaken dormant stem cells in the organ of adults.
