Researchers at the University of Southern California identified a gene that may help regenerate damaged heart tissue after a heart attack. in the journal Nature Genetics. Declining Regenerative Heart Cells with AgeAt birth, we have many mononuclear diploid cardiomyocytes (MNDCMs), heart muscle cells with strong regenerative power. As we age, MNDCM levels drop sharply. By … Continue reading How mice and zebrafish are unlocking clues to repairing damaged hearts
