supply. Surgery can help, but recovery is long and tough. Researchers at Northwestern University have created a new bioactive material that regenerates high-quality cartilage in animal knees.
This breakthrough builds on a 2021 study where “dancing molecules” helped repair spinal cord injuries by activating gene expression needed for tissue regeneration. The same molecules triggered cartilage cells to produce proteins for repair within days. The molecules’ motion is key to stimulating growth.
