The chemokine stromal-cell derived factor-1alpha (SDF1) is the major chemotactic stimulus for human hematopoietic stem cell (HSC) and through its receptor CXCR4 is critically involved in directional migration and homing of hematopoietic progenitors and stem cells. Usually HSC mobilization is achieved after a proteolytic disruption of SDF1-CXCR4 axis after G-CSF administration. Several report showed HSC circulating during early post transplant phase but the mechanism of recirculation is not … Show more
