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 AND CONCLUSION: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.

OBJECTIVE:
To investigate the association of fetal cardiac structural abnormalities with chromosomal aneuploidies and copy number variations (CNVs) in amniocytes.
METHODS:
328 pregnant women were subjected to fetal ultrasonography and chromosomal microarray analysis (CMA). Based on the fetal heart structure, the subjects were divided into normal (n=273) and abnormal groups (n=55). The detection rates of chromosomal aneuploidies and CNVs were compared between the two groups. Spearman method was used to assess the association between the results and fetal cardiac structural abnormalities.
RESULTS:
The detection rates for chromosomal aneuploidies and CNVs in the abnormal group were significantly higher than that in the normal group (P< 0.05), and the incidence of fetal cardiac structural abnormalities was strongly associated with chromosomal aneuploidies and CNVs (P< 0.05).
CONCLUSION
Fetal chromosomal aneuploidies and CNVs are strongly associated with cardiac structural abnormalities.
