Intervertebral disk degeneration (IDD) is a main contributor to low back pain. Oxidative stress, which is highly associated with the progression of IDD, increases senescence of nucleus pulposus-derived mesenchymal stem cells (NPMSCs) and weakens the differentiation ability of NPMSCs in degenerated intervertebral disks (IVDs). Quercetin (Que) has been demonstrated to reduce oxidative stress in diverse degenerative diseases.
