A Critical Analysis of Properties Commonly Ascribed to Stem Cells,potent stem cells stand out, and profoundly differ from all other cells that exist in the organism. On the basis of these observations, an alternative definition of stemness is presented in the next chapter.

Other alleged tissue-specific stem cells, have an oligopotent or a unipotent phenotype and share only one common property with the others, i.e. being the precursors of mature cells of their organ of residence. This raises doubts as to whether all these cells belong to the same class and whether they are stem cells at all.
