Core Tip

Core Tip: To date, there has been no effective treatment for intervertebral disc degeneration (IDD). Nucleus pulposus-derived mesenchymal stem cells (NPMSCs) showed encouraging results in IDD treatment, but the overexpression of reactive oxygen species (ROS) impaired the endogenous repair abilities of NPMSCs. 6-gingerol efficiently decreased ROS levels, attenuated hydrogen peroxide-induced NPMSC apoptosis, and protected the ECM from degeneration, representing a promising candidate for treating IDD.
