Scientists in Sweden have created a cell-free cartilage scaffold that helps the body regenerate damaged bone. The material was created by removing cells from cartilage while preserving its structure and natural growth signals. This material serves as a blueprint for the body's own repair process. In animal studies, it promoted bone regeneration without inducing strong immune responses. The main finding is that the scaffold effectively leads to new bone growth. The team plans to scale up production and begin clinical trials on humans.
