Stromal cell-derived factor 1 (SDF-1), also known as CXCL12, is a chemokine that plays a crucial role in the regulation of stem cell trafficking, tissue repair, and immune responses. SDF-1 is produced by various cell types, including stromal cells, endothelial cells, and certain immune cells. It is known to interact with the chemokine receptor CXCR4, which mediates its biological effects.
