Description

Ten researchers in China searched for the cells that help a torn knee meniscus heal, in work published in 2026. The meniscus is a pad of cartilage in the knee, and its inner part has no blood supply, so it heals poorly. The team wanted to find which cells move in after injury and what they turn into. They used human tissue samples and a rabbit model of injury.

Gene tests on single cells found a group of cells from the joint lining that make large amounts of a protein called periostin. After injury, these cells grew fast, moved to the wound, and later turned toward a cartilage-like state. A gene switch named TCF7L1 seemed to guide this shift. When the team placed these cells into injured knees in rabbits, healing improved, which marks them as a target for new care.
