Conclusion : Using CD34 immunoaffinity column the hematopoietic stem and progenitor cells can be enriched efficiently and the separated CD34 + cells have obvious expansion efficiency and ability of CFU GEMM forming .

结论：CD34免疫亲合柱应用于脐血造血干祖细胞的分离可充分富集CD34+细胞，且分离后的CD34+细胞具有明显的增殖效应和CFUGEMM形成能力。

Results : APS and the conditioned media of bone marrow stromal cell ( BMSC ), endothelial cell ( Ec ), monocyte ( Mc ) induced by APS markedly promoted the proliferation and differentiation of early multipotential progenitor cell ( CFU GEMM );

结果：APS在体外可促进髓系多向造血祖细胞CFUGEMM增殖分化；APS诱导制备的骨髓基质细胞、内皮细胞、单核细胞培养上清液富含造血生长因子活性；

The hematopoiesis of recipient mice was observed in 20 and 40 days post transplantation . Blood RBC and WBC were counted , and nucleated cells , CFU S , CFU GM , CFU E and CFU GEMM were assayed in recipient bone marrow .

在骨髓移植后20和40天，分别检测骨髓移植小鼠外周血RBC，WBC和骨髓有核细胞数及骨髓中CFUS，cFUGM，CFUE和CFUGEMM数。
