Patients with LBP lasting 3 months or longer after conservative treatment. 4. Visual analogue scale of 4 or higher. 5. Oswestry disability index of 30% or higher. 6. MRI shows that the CEPs of the L4-5 IVD is Modic type I or II; 7. MRI shows that the L4-5 IVD is Pfirrmann grade 3, 4 or 5; 8. Discography of lumbar IVD(s) identified as degenerated by MRI show(s) that the patients have only one disc of L4-5 level with similar pain as usual. 9. Patients with =20% loss of lumbar disc height compared to normal adjacent discs based on X-ray assessment. 10. Patients with no active infection (such as HBsAg, HIV, CMV and rubella virus).
Exclusion criteria
Exclusion criteria: 1. Patients with spondylitis or vertebral fractures. 2. Surgery is required for patients with severe lumbar spinal stenosis or prolapse of the lumbar nucleus pulposus resulting in severe nerve compression and pain in the lower limbs. 3. Patients who have received any intradiscal injection procedure (eg, injection of corticosteroids, methylene blue, dextrose, or glucosamine and chondroitin sulfate) within the three months prior to receiving transplantation therapy. 4. Dynamic X-ray examination of the lumbar spine shows that the adjacent vertebral body slips > 3 mm or is angled > 15°. 5. Patients with severe osteoporosis with a bone mineral density (BMD) T value of -2.5 or lower on dual energy X-ray absorptiometry (DEXA). 6. Pregnant or lactating women, or women who become pregnant within 24 months after receiving intervention. 7.
