I cloned myself...
- Background: Bryan Johnson, known for his anti-aging efforts, announced he has “cloned himself.” In reality, he generated induced pluripotent stem cells (iPSCs) from his own blood.
- The Process:
- Drew 125 ml of blood.
- Separated the cells and applied Yamanaka factors to reset their epigenetic age to zero.
- Result: embryonic-like cells that can differentiate into any cell type – essentially “baby Bryans” in a dish.
- Why It Matters:
- After being diagnosed with autoimmune gastritis and his partner Kate with endometriosis, Johnson shifted focus to disease resolution.
- These stem cells could theoretically rebuild damaged organs, such as the stomach lining, kidneys, or liver.
- Future and Costs:
- The technology is currently very expensive, but scalable. Johnson aims to reduce costs so that everyone can access these raw materials for repair.
- With AI and biotech, individuals can now actively tackle their own diseases – a new era of personalized medicine.
Takeaway: Johnson did not create actual human clones, but rejuvenated his cells into versatile stem cells. This breakthrough offers promise for regenerative medicine.
