CXCL12/stromal cell-derived factor 1 is a member of the CXC family of chemokines that plays an important role in hematopoiesis and signals through CXCR4 and CXCR7. Two splice variants of human CXCL12 (CXCL12alpha and CXCL12beta) induce chemotaxis of CXCR4(+) cells and inhibit X4 infection. Recent studies described four other novel ... More
