摘要 本文利用桥联酶标APAAP技术,用CD34+单抗QBEND10标记脐血和外周血造血干细胞,同时采用体外半固体培养法检测脐血和外周血CFU-GM产率血,并对两者的相关性进行了分析。结果表明:(1)体外培养CFU-GM产率,脐血为96.06±63.37,外周血为7.24±6.20,两者差异显著,P<0.01。(2)CD34+细胞百分率,脐血为1.69±1.06%,外周血为0.0065+0.0047%,两者差异显著,P<0.01。(3)脐血CFU-GM产率与CD34+细胞百分率呈正相关,R=0.759,P<0.01,回归方程Y=0.0127X+0.4649。外周血不相关R=0.0447,P<0.05。提示采用桥联酶标法检测CD34+细胞百分率可以代替CFU-GM用于预测脐血造血重建能力,由于该法简便、快速、敏捷,不需昂贵设备。
