BCL2 and Intervertebral disk degeneration: In this experiment, we attempted to investigate the relationship between the expression of Fas and Bcl-2 in the nucleus pulposus cells and apoptosis of nucleus pulposus cells to further elucidate the role of Fas and Bcl-2 in the nucleus pulposus cell apoptosis, intervertebral disc degeneration, and disc herniation and then provide theoretical support for exploring a more rational treatment of lumbar disc herniation.
