摘要
目的 建立脐血造血干细胞库,用于治疗白血病、淋巴瘤、再生障碍性贫血等疾病。方法 采集新生儿脐血,用6%HES离心法分离脐血有核细胞以缩小脐血体积,样本以10%DMSO保存,检测有核细胞数、CD34+、CFU-GM及HLA,并作病原学捡测。结果 收集590份脐血,合格230份(合格率39%),平均脐血体积(89±20)ml,平均有核细胞数(1.48+0.36)×10~9,分离后有核细胞数(1.25±0.28)×10~9,有核细胞回收率(91+7)%,脐血CD34+细胞的百分率为(0.37±0.26)%,复苏后CFU-GM回收率为84%,平均每份脐血含CFU-GM(0.9±0.4)×10~6个集落,14%的样本CMV抗体阳性。73人查询,HLA 4个抗原以上相合率为95.7%。至2001年7月,提供3份脐血用于非亲缘脐血移植,1份用于亲缘脐血移植,3例植入,1例排斥。结论 建立脐血库有良好的应用前景。
