Animal models have added significantly to our understanding of the mechanism(s) of hematopoietic stem and progenitor cell (HSPC) mobilization. Such models suggest that changes in the interaction between the HSPC and the hematopoietic microenvironmental ‘niche’ (cellular and extracellular components) are critical to the process. The increasing availability of recombinant proteins (growth factors, cytokines, chemokines), antibodies, drugs (agonists and antagonists), and mutant and genetically modified animal models [gene knock-in (KI) and knock-out (KO)] continue to add to the tools available to better understand and manipulate mobilization processes.
