1、Stem cells have the potential to differentiate into any cell type in the body, but they become unipotent as they specialize into a specific cell lineage.
干细胞具有分化成身体内任何类型的细胞的潜力，但当它们专门化为特定的细胞系谱时，它们变得单能性。

2、In biology, unipotent refers to stem cells that can only differentiate into one type of mature cell.
在生物学中，单能性指的是只能分化为一种类型的成熟细胞的干细胞。
