胚胎干细胞 ESC (embryonic stem cell)
- 许多专家把使用胚胎干细胞看作一种可行的治疗各种疾病的方法。
Many experts see the use of embryonic stem cells as a possible way to treat diseases. - 基于成人干细胞的研究可能是有前途的,不过比不上基于胚胎干细胞的研究。
Research based on adult stem cells may be promising, but not nearly as promising as that based on embryonic ones. - 例如,未分化的胚胎干细胞可能形成肿瘤,如果在移植前细胞未全部成功分化,将可能造成癌症。
Undifferentiated ES cells can form tumors, for instance, creating a risk of cancer if the cells are not all successfully differentiated before transplantation.
