  "summary": "Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and may drive the ligament overgrowth that squeezes spinal nerves and causes pain, numbness, and difficulty walking. Researchers found that reducing calcium signaling stopped this abnormal growth in mice.",
