Could cord blood ease your back pain? early trial tests new approach

This is a very early, small study to first check if a special cord blood product (CFL001) is safe for people with chronic pain in the sacroiliac joint, a common cause of lower back pain. Nine adults with significant, long-lasting pain who haven't gotten enough relief from standard treatments will receive an injection into the painful joint. The main goal is to see how well different doses are tolerated, while also looking for early signs that it might help reduce pain and improve daily life.
