The Safety/Efficacy Study of Human Umbilical Cord Mesenchymal Stem Cells Therapy (19#iSCLife®-LDP) for Lumbar Discogenic Pain

This study tests whether injecting human umbilical cord mesenchymal stem cells into damaged spinal discs can relieve chronic low back pain (lumbar discogenic pain). Stem cell therapy aims to regenerate the disc and reduce inflammation as an alternative to surgery. You may be eligible if: - You are 18 or older - You have had persistent low back pain for more than 6 months that has not responded well to conservative treatment - Your MRI shows disc degeneration without severe prolapse or nerve compression - Your straight leg raise test is negative (70 degrees) You may NOT be eligible if: - You have a blood clotting disorder or are on anticoagulant therapy - You have an active infection in the spine or injection site - You have had prior back surgery or other disc treatments - You are pregnant or breastfeeding - You have active cancer or elevated tumor markers - You have a substance abuse problem or mental illness affecting cooperation Talk to your doctor to see if this trial is right for you.
