Haemopoietic stem and progenitor cells from bone marrow and cord blood are well characterised with respect to their phenotype, growth in clonal assays, responsiveness to cytokine stimulation, receptor profile and their ability to sustain multilineage engraftment of receptive hosts in animal models of transplantation and of course, clinically in the treatment of some haemopoietic and immunological disorders. It is generally accepted that cells bearing the CD34+ phenotype are enriched for the most primitive of haemopoietic stem cells that possess the cardinal features of self-renewal and multipotency. However, the molecular mechanisms, the spectrum of expressed genes that give rise to the physical characteristics of haemopoietic progenitor cells are not well understood. Furthermore, although CD34+ cells from different sources (bone marrow, cord blood, mobilised peripheral blood) share many common features, there are also significant differences.
