The human heart can’t repair itself after injuries. But now, heart regeneration has been made possible, thanks to two stem cell types.
Unlike some animals, humans lack the ability to regenerate dead muscle tissue after injuries like a heart attack.
However, the heart controls the damages by changing the dead cells into scar tissue. Unfortunately, this process limits the heart’s ability to contract and pump blood properly.
Heart failure is a deadly condition that takes millions of lives around the world every year. But now, stem cell scientists are getting closer to fixing damaged hearts through regeneration.
