Local clearance of senescent cells attenuates the development of post-traumatic osteoarthritis and creates a pro-regenerative environment

Researchers studied knee injuries in mice and examined cartilage samples from people with osteoarthritis. They removed senescent cells, which are damaged cells that stop dividing and release harmful signals, using genetic methods and an injected drug. The treated mice developed less post-traumatic osteoarthritis, meaning joint damage after an injury, and showed more cartilage repair. The study did not test this treatment in people.

What this means for you: This is promising for future treatments after knee injuries, but it does not show that buying or taking a senescent-cell treatment helps people. You can ignore products making that claim for now.
