Core Tip
Core tip: The chemokine stromal cell-derived factor-1α (SDF-1α) is upregulated in the pro-inflammatory microenvironment or degenerative intervertebral disc (IVD). The present study demonstrates for the first time that SDF-1α effectively promotes migration and chondrogenic differentiation of nucleus pulposus-derived stem cells (NPSCs), which serve as endogenous progenitor/stem cells residing in the IVD. In addition, SDF-1/CXCR4 chemotaxis signals may play a crucial role in the process of recruitment and chondrogenic differentiation of NPSCs that are involved in spontaneous IVD regeneration in the early stage of IVD degeneration.
