Breakthrough to Restore Aging Joints Could Help Treat Osteoarthritis

Stanford-led researchers identified 15-PGDH as an aging-linked driver of cartilage loss in osteoarthritis.

Blocking 15-PGDH thickened cartilage in older mice and protected younger injured mice from osteoarthritis-like damage.

The same approach also showed regenerative effects in human knee tissue, suggesting a stem-cell-free path to joint repair.

If confirmed in further studies, this could help preserve mobility, reduce pain, and delay or avoid joint replacement surgery.
