RESUMEN
Objective To investigate the influence factors of peripheral blood hematopoietic stem cell of healthy donor by granu‐locyte colony‐stimulating‐factors(G‐CSF) mobilization .Methods G‐CSF was subcutaneously injected in 24 cases of healthy donor for mobilizing hematopoietic stem cells .The T lymphocyte subgroup and blood routine data were detected .Results After G‐CSF stimulation ,peripheral blood CD3+ (% ) ,CD3+CD4+ (% ) ,white blood cell (WBC) count and platelet were significantly increased (P<0 .05) .And nucleated cells density of bone ,percentage of CD34+ cells on mobilized 4 ,5 ,6 d had no obvious difference .The correlation analysis showed that gender ,age and weight were negatively correlated with CD 34+cells percentage (P<0 .05) and pos‐itively correlated with WBC count (P<0 .01) .Conclusion Male donor is superior to female donor within a certain range ,the smal‐ler age ,the lighter weight ,the higher WBC count ,the higher the percentage of CD34+ cells in peripheral blood hematopoietic stem cells after G‐CSF mobilization .
