与干细胞不同,祖细胞的分化具有更多的明确性,也就是说,只能发化为一些目标细胞.他俩另外一个最重要的区别是,干细胞可以无限增值,而祖细胞分裂的次数是有限的.
在有些情况下,这个两个概念是一样的.

Like stem cells,progenitor cells have a capacity to differentiate into a specific type of cell.In contrast to stem cells,however,they are already far more specific:they are pushed to differentiate into their "target" cell.The most important difference between stem cells and progenitor cells is that stem cells can replicate indefinitely,whereas progenitor cells can only divide a limited number of times.Controversy about the exact definition remains and the concept is still evolving.
The terms "progenitor cell" and "stem cell" are sometimes equated
