We evaluated the teratoma-forming propensity of secondary neurospheres (SNS) generated from 36 mouse induced pluripotent stem (iPS) cell lines derived in 11 different ways. Teratoma-formation of SNS from embryonic fibroblast-derived iPS cells was similar to that of SNS from embryonic stem (ES) cells. In contrast, SNS from iPS cells derived from different adult tissues varied substantially in their teratoma-forming propensity, which correlated with the persistence of undifferentiated cells.
我们评估了由11种不同方式获得的36个小鼠诱导多能干细胞（iPS）系所产生的次级神经球（SNS）形成畸胎瘤的倾向。来自胚胎成纤维细胞衍生的iPS细胞的SNS形成畸胎瘤的情况与来自胚胎干细胞（ES）的SNS相似。相比之下，来自不同成年组织的iPS细胞的SNS在形成畸胎瘤的倾向上有很大差异，这与未分化细胞的持续存在相关。
