EvaluatIon of Autologous Nucleus Pulposus Cells (aNPC) in Degenerative Disc Disease

Eligible subjects must be diagnosed with disc herniation and scheduled for discectomy, nucleus pulposus tissue will be collected for cell culture. Cultured cells will be then reintroduced into the degenerated disc via injection. Subjects will undergo multiple follow-up visits after surgery to evaluate safety and efficacy, supplemented with imaging studies to assess disc height, tissue regeneration, and water-retention capacity.
