How Scar Tissue can be Turned Back into Functioning Heart Muscle

Following a heart attack, the muscle cells of the heart, referred to as cardiomyocytes, die in the affected area. The cells of the heart, like those of the brain, are unable to regenerate. This weakens the heart muscle which is then unable to carry out its pumping function efficiently and a large damaged area can result in heart failure. Scientists compared reprogrammed cardiomyocytes produced by two different techniques - the iPSC-CMs and iCMs. Stem cells help produce new muscle from scar tissue after a heart attack.
