Stanford University scientists have discovered a method to regrow cartilage in the human body, which could potentially treat and prevent arthritis. The researchers used a combination of a biomaterial scaffold, growth factors, and stem cells to create a functional cartilage tissue. In a study involving rabbits, the team was able to successfully regenerate cartilage in the animals' knees, allowing them to walk and move without pain. The scientists believe that this breakthrough could lead to new treatments for osteoarthritis, a condition that affects millions of people worldwide. The study's findings were published in the journal Nature Communications.
