Why zebrafish hearts heal so well: Early immune signals can improve repair even further
When the human heart is damaged by a heart attack, stiff scar tissue eventually forms around the affected areas. This weakens the heart's pumping ability and increases the risk of heart failure and arrhythmias. Zebrafish, ...
