          Stromal cell-derived factor-1 beta (SDF-1β), the beta splice variant of the CXCL12 gene, is one of two SDF-1 splice variants made by a wide variety of cells upon stimulation by inflammatory cytokines such as TNF, IL-1, and LPS. SDF-1 β signals through the G protein-coupled receptor CXCR4 to recruit activated leukocytes.
