Study suggests 156-year ceiling if somatic mutations are neutralized

A July 2026 npj Aging paper from Russia suggests humans could live as long as 156 years if the effects of somatic mutations were removed, though other aging processes and non-regenerating brain and heart tissues still limit healthy years; meanwhile, lifestyle factors like not smoking, maintaining a healthy weight, vaccines, and cancer screenings can add about a decade to life expectancy, with the current oldest person at 116 illustrating present limits.

Regenerative gene therapy aims to bulk up failing hearts, now in human trials

Scientists are pursuing RNA-delivering gene therapies to disable a brake on heart-cell division in hopes of regenerating failing hearts; early animal data show improved heart function and a first-in-human trial began, but the field remains cautious due to uncertain evidence of true regeneration and a history of controversial retractions.

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.

Scientists Discover Heart's Natural Ability to Heal and Regenerate

Scientists at Mount Sinai have discovered that reactivating the Cyclin A2 (CCNA2) gene in adult hearts can promote self-healing after injuries like heart attacks, potentially revolutionizing treatment by enabling natural heart regeneration and reducing reliance on transplants or mechanical devices.

Scientists Discover Heart Regeneration Method Using Cyclin A2

Scientists at Mount Sinai have discovered a method to stimulate adult human heart cells to divide and regenerate by reactivating the dormant gene CCNA2, potentially leading to new treatments for heart damage and reducing the need for transplants.

Unveiling the Key Mechanism for Heart Regeneration: Repairing a Damaged Heart

Researchers have discovered a mechanism involving LRRC10 in zebrafish that promotes the maturation of heart muscle cells during the regeneration process. This finding, applicable to human cells, could lead to new treatments for cardiovascular diseases by replacing lost heart tissue. The study shows that examining the natural heart regeneration process in zebrafish and applying these discoveries to human heart muscle cells may contribute to the development of therapies against cardiovascular diseases, which are a leading cause of death worldwide.

Scientists Overcome Roadblock to Human Heart Regeneration

Scientists at the University of Washington School of Medicine have used CRISPR-based genome editing to create stem cells that do not cause dangerous arrhythmias, a major complication previously hindering stem-cell therapies for injured hearts. The team created a new line of cells called “MEDUSA,” which engraft in the heart, mature, and integrate into heart muscle without generating dangerous heart rates. This breakthrough could pave the way for safe and effective stem cell therapy for heart regeneration.
