Enhanced functional response to CXCL12/SDF-1 through retroviral overexpression of CXCR4 on M07e cells: implications for hematopoietic stem cell transplantation.


The chemokine CXCL12 (stromal cell derived factor-1/SDF-1) stimulates hematopoietic stem and progenitor cells (HSCs/HPCs) through the corresponding chemokine receptor CXCR4. CXCL12 is thought to be important for both proper HSC homing, retention, and engraftment into the bone marrow (BM) and mobilization out of the BM. Previous studies suggest that breaking… (More)
