This image shows the Patellar tendon 30 days after an injury. The red marks newly discovered tendon stem cells that have self-renewed and are layered over green marked, original tendon cells. During regeneration, some tendon stem cells differentiate to make newly regenerated tendon cells—a process during which they transition into a yellow-orange color. The blue indicates cellular nuclei.

Discovery of tendon stem cells could be a game-changer when it comes to treating tendon injuries, avoiding surgery. The buildup of scar tissue makes recovery from torn rotator cuffs, jumper’s knee, and other tendon injuries a painful, challenging process, often leading to secondary tendon ruptures...
