Abstract:

BACKGROUND: The number of hematopoietic stem cells in the peripheral blood is very low at normal physiological state. So it is critical to mobilize hematopoietic stem cells 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 cells 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 cells in the peripheral blood and bone marrow were collected. CD34+ cell 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 cells was identified by cell colony forming assay.
RESULTS AND CONCLUSION: The concentration of CD34+ cells 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 cells were all improved by both AMD3100 and dexamethasone and especially their combined use. This indicates that both AMD3100 and dexamethasone could mobilize hematopoietic stem cells 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.
