Patent ID: 7799528

Claim:
A method of determining whether a first population of human cells comprises CD34 + CD38 − Lin − hematopoietic stem cells, comprising the steps of: (a) enriching the first population of cells for cells displaying the CD34 antigen in a bone marrow, peripheral blood, or umbilical cord blood sample; (b) determining the level of expression of CEBPB, GATA3, HLF, HOXA3, HPIP, KLF2, KLF4, MDS1 and NRIP1 in the population of cells of (a), wherein higher expression of CEBPB, GATA3, HLF, HOXA3, HPIP, KLF2, KLF4, MDS1 and NRIP1 in the first population of human cells compared to a control human CD34 + CD38 + Lin + hematopoietic progenitor cell population indicates that the first population of cells comprises CD34 + CD38 − Lin − hematopoietic stem cells.
