Research Abstract |
We generated mice that allowed selective ablation of CAR cells within bone marrow and determined the in vivo function of CAR cells as a niche for hematopoietic stem cells (HSCs) and lympho-hematopoietic progenitors. Short-term ablation of CXC chemokine ligand (CXCL)12-abundant reticular (CAR) cells in vivo severely impaired the production of SCF and CXCL12, and led to a marked reduction in cycling lymphoid and erythroid progenitors. HSCs from CAR cell-depleted mice were reduced in number and cell size, were more quiescent and had increased expression of early myeloid selector genes. Thus, CAR cells are the major producer of CXCL12 and SCF and are required for proliferation of HSCs and lymphoid and erythroid progenitors as well as maintenance of HSCs in an undifferentiated state.
