New Research Finds Regeneration in Human Heart Cells After Attack

Researchers analyzing living human heart tissue found that heart muscle cells can divide after a heart attack, indicating potential regeneration in humans. By examining tissue from a donor heart and bypass patients and using RNA sequencing, they identified conditions that promote cardiomyocyte division. While promising, the findings do not yet prevent scar formation or heart damage, but could guide future regenerative therapies, and were published in Circulation Research.
