Engineered Cells Reverse Aging in Primates

Scientists reversed aging in elderly macaques using engineered cells, showing promise for human applications.

Why it matters

  • Shows potential for reversing aging in humans.
  • Could improve quality of life and treat age-related diseases.

By the numbers

  • 44-week experiment on elderly macaques.
  • Biweekly injections of 2×10⁶ cells/kg.
  • Reversed aging markers in 10 systems and 61 tissues.
  • Biological age reversal: neurons by 6-7 years, oocytes by 5 years.

The big picture

  • SRC therapy offers a systemic anti-aging intervention.
  • Exosomes from SRCs are key agents of rejuvenation.

What they're saying

  • Skepticism about long-term impact.
  • Interest in specific applications like tendon rejuvenation.
  • Broader implications and conspiracy theories discussed.

Caveats

  • Study conducted on macaques, not humans.
  • Long-term effects and safety in humans unknown.

What’s next

  • Further research needed for human trials.
  • Understanding long-term effects and safety.
