Young mice can regenerate their heart after injury

Scientists at the Southwest Medical Center, University of Texas (USA) have discovered the heart of newborn mammals that can restore function after injury.

Scientists led by Dr. Hesham Sadek, of the Southwest Medical Center conducted experiments on mice. The study found that if a part of the heart of mice born at one week of age was removed, their hearts could fully heal themselves.

According to scientists, for experimental rats, the maximum limit for cardiac resection is 15% of the entire heart. Within this range, with a three-week period, newborn mice can recover and heal lost tissue. However, usually after 7 days, this miraculous regeneration function will disappear, the problem of heart failure reappears

According to Dr. Hesham Sadek, the healthy heart cells of newborn mice can become a source of material to produce new cells, while stem cells can also help with this process.

Scientists have discovered the heart of adult zebrafish after being injured and can regenerate new heart. This miraculous phenomenon can also be observed in some fish and other amphibians.

Scientists will continue to study this issue in the hope that in the future it can be applied to treat heart disease in humans.
