| 摘 要： | 目的体外分离培养人新鲜脐血（UCB）造血干细胞（HSC），利用骨髓间充质干细胞作为滋养层联合细胞因子组合以扩增脐血造血干／祖细胞。方法采用Ficoll淋巴细胞分离液密度梯度离心法分离UCBHSC，加入骨髓间充质干细胞和细胞因子，检测脐血造血干／祖细胞总有核细胞（NC）总数和CD34^＋细胞数。结果有核细胞总数扩增（75．2±15．0）倍，CD34^＋细胞数扩增（18．7±12．3）倍。结论体外HSC培养，加入骨髓间充质干细胞和细胞因子对造血干／祖细胞增殖有明显的作用。 |

| Abstract: | Objective To separate and cultivate homo umbilical cord blood (UCB) hematopoietic stem cell (HSC) in vitro, and u-tilize bone marrow desmohemoblast stem cell as trophoblastic layer combined with cytokine to amplify umbilical cord blood hematopoietic stem/progenitor cell. Methods Ficoll lymph-cell separating medium density gradient centrifugalization was used to segregate UCBHSC.Bone marrow desmohemoblast stem ceil and cytokine were added, and the sum of NC cells and CD34 + cells was counted. Results The sum of NC cells amplified 75.2±15.0 times, and the sum of CD 34 + cells amplified 18.7±12.3 times. Conclusions It has significant effect on amplification of hematopoietic stem cell with bone marrow desmohemoblast stem cell and eytokine when HSC are cultured in vitro. |
