Embryonic stem cells, which replicate indefinitely in the culture dish, are capable of forming almost any tissue in the body.
胚胎干细胞，在培养基中不确定的复制，有能力形成身体几乎所有的组织。
Cells from the blastocyst then were cultured in a lab dish and yielded stem cells that were an exact match to the donor's DNA.
之后科学家从囊胚中提取出细胞，并在培养皿里培育成干细胞，干细胞的DNA与那名成熟细胞捐献者的DNA完全一致。
The results, he says, would contribute to scientists' understanding of the full pathway of genes needed to prompt differentiation of neural stem cells both in the brain and in the culture dish.
这些结果，他说，将有助于科学家理解神经干细胞需要迅速分化的所有基因的途径，无论在大脑还是培养基。
For example, nitric oxide could be used to grow and expand blood stem cells either in the culture dish or in patients after transplantation.
例如，氧化一氮能被用于在移植以后生长和扩展血液干细胞在培养皿或在患者。
Larry Goldstein: Stem cells are giving us a way, for the first time, to have true human brain cells in a dish that carry the genetic changes that we know can contribute to or cause disease.
生物学家对胚胎干细胞的研究从未停止过，通过干细胞，科学家首次得以方便地制造出人脑细胞，从而研究致病的遗传改变。 现在他们在这一方面的进展如何？ 且看下文分解。
