Cell bodies and processes of CXCL12-abundant reticular (CAR) cells, which create a niche for hematopoietic stem and progenitor cells (HSPCs), can be observed in the bone marrow of CXCL12-GFP knock-in mice.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
CXC chemokine ligand 12 (CXCL12), also known as stromal cell-derived factor (SDF)-1 or pre-B cell growth-stimulating factor (PBSF) was characterized initially as a growth factor for B cell precursor clones. CXCL12 stimulation is mediated by the G protein-coupled receptor CXCR4. Studies using conventional and conditional knockout mice revealed that CXCL12-CXCR4 signaling has an essential role in hematopoietic stem cell (HSC) maintenance, B cell and germ cell development, neurogenesis, cardiogenesis, and vascular formation [1-4]. Nagasawa and colleagues have revealed the role of CXCL12-abundant reticular (CAR) cells, which are a population of stromal cells that are scattered throughout bone marrow and express high levels of CXCL12 [5, 6]. Recently, they determined a critical role for CAR cells as a microenvironmental niche for HSCs and lymphoid and erythroid progenitors [7-9]. Analyses of CXCL12-CXCR4 signaling in vivo<\/i> will clarify the molecular mechanisms underlying microenvironmental niche formation in mammals.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
