<p>Disclosed herein is the discovery that mammalian stem cells do not express β2microglobulin(β2m). The invention discloses a method of isolating stem cells comprising sorting, from a sample of cells, cells that express β2m from cells that do not express β2m. One then selects stem cells from the population of cells that does not express β2m. This is accomplished by selecting cells that express a known marker, such as proteins expressed by genes encoding the major histocompatibility complex. An isolated stem cell is disclosed, as is a method for identifying it and other stem cells.</p> |
