Methods, compositions and cells are provided that identify and isolate a population of adult non-embryonic progenitor cells having multilineage potential, physical diameters of about 2 &#x3bc;m to about 8 &#x3bc;m in size or about 4 &#x3bc;m to about 6 &#x3bc;m, and expressing at least one of the stem cell associated genes among Oct-4, KLF-4, Nanog, Sox-2, Rex-1, GDF-3 or Stella. Methods are also provided that identify and isolate populations, which are subsets or subpopulations of progenitor adult stem cells within the population of the adult stem cells which is a heterogeneous population, the methods including contacting the adult stem cells with a ligand specific for at least one of: CD99, tetraspan, ICAM4, full-length MUC1, and truncated MUC1 receptor, in which a presence of a surface protein on the cells that bind to the ligand identifies the population which is the subset of the differentiated progenitor adult stem cells.
