这项研究其实就是将成熟的细胞返祖，变成类似于胚胎状态的细胞。

The technique essentially reverts mature cells to an embryo-like state.

这个日本的研究小组使用了老鼠的干细胞——有能力转变为多种体组织的未成熟的细胞。

The Japanese team used mouse stem cells - immature cells that have the ability to turn into many types of body tissue.

The other property is that these committed progenitor cells that are formed can turn into something, can turn into more mature cell types.

另一个的性质就是成为定向祖细胞,进而形成某种特定细胞,成为更成熟的细胞形式
