Highly concentrated hematopoietic stem cell compositions are provided which are substantially free of differentiated or dedicated hematopoietic cells.

The resulting composition may be used to provide for individual or groups of hematopoietic lineages, to reconstitute stem cells of the host, and to identify an assay for a wide variety of hematopoietic growth factors.
