Abstract
A method for obtaining human hematopoietic stem cells is provided by enrichment for stem cells using a novel stem cell marker. Compositions enriched for stem cells are obtained using novel antibody HCC-1 which is specific for a CD59 epitope highly accessible on stem cells, and less accessible or absent on mature cells. The enriched population of cells derived from these methods are also provided.
