Aspects of the present invention relate to methods to differentiate pluripotent primordial stem cells, such as human embryonic stem (“hES”) cells, human embryonic germ (“hEG”) cells, human embryo-derived (“hED”) cells and human embryonal carcinoma (“hEC”) cells, to obtain subpopulations of cells from heterogeneous mixtures of cells, wherein the subpopulation of cells possess reduced differentiation potential compared to the original pluripotent stem cells and where the subpopulation is capable of being propagated 20 or more population doublings. This invention also provides novel compositions of such subpopulations of cells and methods to propagate and differentiate said cells.
