The human heart is an organ whose cells rarely divide, making tissue repair and regeneration a huge problem following a heart attack. Many animals, such as zebrafish and salamanders, are different; they can regenerate damaged hearts easily.
As humans, we also once had the same regenerative capacity during our early development, but after we were born, we lost this ability. This is also true for many other organs, including the brain, spinal cord, and pancreas. The cells in these tissues divide very rarely if at all, and this is a big problem. But, what if we could get that regenerative ability back and repair damage to our hearts the way these amazing animals do?
Researchers have been trying for decades to find out how we can enjoy the same tissue regeneration, but they have met with limited success—until now.
