- The teams reported that they found the new cells in the innermost cell layer, the epiblast, of one week old rodent embryos, rather than in a ery early stage embryo where ordinary ES cells are found. 这个研究小组报道称他们在一周大的,啮鼠动物的外胚层细胞层的最里发现这些新细胞，比起早期每个阶段胚胎的胚胎干细胞发现的地方，这里更多些。
- But when the endodermal nuclei of neural-plate cells were transplanted into enucleated eggs, only half of the blastulae underwent gastrulation and tten the development was arrested. 在以神经板期内胚层细胞核为供体的移植过程中,虽有一半以上的全囊胚发育到原肠期,但是胚胎进一步发育的能力受到较明显的阻抑。

- According to NIH team leader Ronald McKay, that means epiblast cells offer scientists a iew of an ES cell just as it's poised to produce mature cell types, including neurons, muscle and bone. 根据美国国家卫生所的研究小组负责人RonaldMcKay的说法：这就意味着外胚层细胞给予科学家一种胚胎干细胞全新的观点，那就是他是一种制造成熟细胞类型，其中包括神经，肌肉和骨的一种平衡。
