目的 探讨基于测序的人类白细胞抗原分型(HLA-sequencing-based typing,HLA-SBT)和PCR短串联重复序列(short tandem repeat,STR)技术在人胚胎干细胞(human embryonic stem cell,hESC)应用前检测中的运用,建立人胚胎干细胞系的基因型档案.方法 人胚胎干细胞系SYSU-I、SYSU-3,分别培养到20代、40代,应用PCR寡核苷酸特异测序探针(sequence specific olignucleotide probe,SSO)技术检测两株细胞系的HLA-A、-B、-DR位点的低分辨分型,再利用HLA-SBT技术检测两株细胞系的HLA-A、-B、-DR位点的高分辨分型.应用PCR-STR技术检测两株细胞系的基因遗传标记.结果 获得两株hESC细胞系的HLA高分辨分型和STR基因型.结论 可以运用HLA-SBT和PCR-STR技术建立人胚胎干细胞应用前的基因型档案.
