ABSTRACT
BACKGROUND:
The number of hematopoietic stem cel s in the peripheral blood is very low at normal physiological state. So it is critical to mobilize hematopoietic stem cel s from donor’s bone marrow into the peripheral blood.OBJECTIVE:
To study the combination effect of AMD3100 and dexamethasone on the mobilization of hematopoietic stem cel s in mice, thereby laying the foundation for clinical application.METHODS:
C57BL/6 mice were injected with AMD3100 and dexamethasone alone or in combination. Then, hematopoietic stem cel s in the peripheral blood and bone marrow were col ected. CD34+cel concentration in the peripheral blood and bone marrow was determined by flow cytometer and the content of leucocytes in the peripheral blood was counted by a normal method. The CFU-Mix colony formation ability of hematopoietic stem cel s was identified by cel colony forming assay. RESULTS ANDCONCLUSION:
The concentration of CD34+cel s in the peripheral blood and bone marrow, the content of leukocytes in the peripheral blood and the CFU-Mix colony formation ability of hematopoietic stem cel s were al improved by both AMD3100 and dexamethasone and especial y their combined use. This indicates that both AMD3100 and dexamethasone could mobilize hematopoietic stem cel s to migrate from the bone marrow to the peripheral blood, and when used in combination, the mobilization effect is better than that of single drug.
