Summary

In recent years, total endoscopic extraction of nucleus pulposus has been widely used in the treatment of lumbar disc herniation due to its advantages of less trauma, faster recovery and less cost. However, the residual nucleus pulposus may protrude again after extraction, and the stability of the operative segment decreases and the degeneration of the diseased segment accelerates. Therefore, while decompression of nerve root is completed under total endoscopic nucleus pulposus extraction, tissue engineering of nucleus pulposus is urgently needed to replace the lost part, repair the remaining nucleus pulposus, and enable the disc to be re-sealed and pressurized. Nucleus pulposus tissue engineering is mainly based on cell therapy, and the corresponding biological scaffolds are selected to transplant cells into the diseased area for treatment. However, the current nuclear tissue engineering has some shortcomings, such as limited seed cell source, difficult survival of seed cells, inflammatory rejection in the transplantation area, poor mechanical properties of biological scaffolds, poor degradation performance, and inability to produce biospecific reactions between materials and cells, which seriously restrict the clinical application of nuclear tissue engineering. Human umbilical cord mesenchymal stem cells (hUC-MSCs) are ideal seed cells for the treatment of lumbar disc herniation due to their wide availability, strong proliferation ability and good immune regulation. Therefore, in this project, hUC-MSCs are used for cell transplantation into the vertebral disc of diseased vertebrae. As the treatment method of this project is extremely minimally invasive, it is conducive to the widespread promotion of the technology.

Conditions
