Homing and mobilization of hematopoietic stem cells
Author(s):
Abstract:
Hematopoietic stem and progenitor cells (HSPCs) are non-stop travelers throughout body in both time and space. Understanding the mechanism of HSPCs homing and mobilization is important to enhance the efficacy at bone marrow transplantation and cellular therapy. Mobilized HSPCs has largely replaced than the use of bone marrow as a source of stem cells for both allogeneic and autologous stem cell transplantation. This review describes the specific factors which play a key role in homing and mobilization of HSPCs, includes SDF-1 and its receptor CXCR4, proteases (MMPs and CPM). Moreover, chemokines inducing rapid HPSCs mobilization would be discussed. In this article we showed that many factors such as adhesion molecules and SDF-1/CXCR4 have critical roles in homing hematopoietic stem cells and G.CSF, MMPs, adhesion molecules and ROS involvement in mobilization of stem cells. According to above, we can be rich the peripheral blood of HSPCS using of this factors and antagonist for this receptors on the osteoblastic cells or/and HSPCs to bone marrow transplant.
