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.
