This unexpected ability opens the door for scientists to stimulate cellular mitosis and improve heart function after an attack.

Your heart will not just give you fear and uncertainty after a heart attack; it can leave scar tissue that stiffens your heart and limits your strength. Many people learn to live with that loss, but ...

UC labs are developing new treatments that don’t just prevent damage from getting worse, but — for the first time in medical ...

Heart attacks remain a leading cause of death and disability worldwide. The permanent loss of heart muscle cells—known as cardiomyocytes—and the heart's limited regenerative capacity often lead to ...

Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers led by Suphansa ...

Artistic representation of heart regeneration: Hmga1 in green symbolically flows from the border zone of a zebrafish heart (top right) to the injured border zone of a mouse heart (left). Red ...

USF Health Heart Institute doctors are upbeat about cardiac regeneration. But when those batteries – heart muscle cells called cardiomyocytes − short circuit and die, the damage can be devastating.

After severe heart failure, the ability of the heart to heal by forming new cells is very low. However, after receiving treatment with a supportive heart pump, the capacity of a damaged heart to ...

It’s active during embryonic development but switches off soon after birth, so reactivating this dormant gene could help repair damage after a heart attack. The team says that the next step of the ...
