| 摘 要： | 比较了不同发育阶段山羊核移植胚胎分离培养胚胎干细胞（NT-ESCs）的情况。结果表明,各阶段山羊核移植胚胎均可分离出NT-ESCs,其中孵化胚的NT-ESCs克隆形成率最高（38%）,与囊胚（26%）差异显著,与桑葚胚（18%）差异极显著。所分离的NT-ESCs细胞形态与正常ESCs相似,均具有碱性磷酸酶活性,可表达多能性基因Oct-4和表面标志抗原SSEA-1。

| Abstract: | The isolated cultures of nuclear transplantation embryonic stem cells(NT-ESCs) from nuclear transplantation embryos of goats in different developmental stages were compared.The results showed that NT-ESCs could be isolated from nuclear transplantation embryos of goats in all developmental stages,among which the cloning efficiency of NT-ESCs from hatching embryos was highest,being 38%;it had significant difference from that of blastula,which was 26% and it had extremely significant difference from that of embryotic sphere,which was 18%.The shape of isolated NT-ESCs was similar to that of normal ESCs,both of them had alkaline phosphatase activities and could express pluripotency gene Oct-4 and surface marker antigen SSEA-1. |
