Core Tip

Core tip: Mesenchymal stem cell (MSC) transplantation shows exciting promise for the future regenerative approach to intervertebral disc (IVD) disease. Extensive preclinical research has demonstrated benefits from MSC treatment in disc degeneration. Cell tracking, with iron oxide nanoparticles and MRI, provides an opportunity to develop an in-depth understanding of stem cell survival, differentiation and migration, enabling optimization of stem cell treatment. This review summarizes the current literature relating to MSC tracking in the IVD, which is limited to short term monitoring. Medium to long-term cell tracking is required to accelerate translation of MSC treatment in the IVD to clinical practice.
