- Stanford scientists have developed a treatment that blocks the aging-related protein 15-PGDH, restoring lost knee cartilage in old mice and preventing arthritis after injuries.
- Human cartilage samples from knee replacement surgeries showed signs of regeneration when exposed to the treatment, raising hopes for a future drug to repair joints without replacement.
- The treatment works by reprogramming existing cartilage cells (chondrocytes) to a more youthful state, rather than relying on stem cells, offering a new approach to tissue regeneration.
- In mice, the treatment prevented osteoarthritis following ACL-type injuries and improved joint function, with both systemic and local injections proving effective.
- An oral version of the 15-PGDH inhibitor is already in clinical trials for age-related muscle weakness, and researchers hope to soon test it for cartilage regeneration in humans.
