  "textContent": "BY THE OPTIMIST DAILY EDITORIAL TEAM A Stanford Medicine study has identified a protein that roughly doubles in aging joints and blocks cartilage from repairing itself. Blocking that protein in older mice regenerated hyaline cartilage across the joint surface. Human tissue samples from knee replacement surgeries responded the same way after just one week of […]\n\nThe post How blocking one protein regenerates knee cartilage in aging mice and human tissue first appeared on The Optimist Daily: Making Solutions the News.",
