We previously identified CD34-negative (CD34−) severe combined immunodeficiency (SCID)-repopulating cells as primitive hematopoietic stem cells (HSCs) in human cord blood. In this study, we develop a prospective ultra-high-resolution purification method by applying two positive markers, CD133 and GPI-80. Using this method, we succeed in purifying single long-term repopulating CD34− HSCs with self-renewing capability residing at the apex of the human HSC hierarchy from cord blood, as evidenced by a single-cell-initiated serial transplantation analysis. The gene expression profiles of individual CD34+ and CD34− HSCs and a global gene expression analysis demonstrate the unique molecular signature of CD34− HSCs. We find that the purified CD34− HSCs show a potent megakaryocyte/erythrocyte differentiation potential in vitro and in vivo. Megakaryocyte/erythrocyte progenitors may thus be generated directly via a bypass route from the CD34− HSCs. Based on these data, we propose a revised road map for the commitment of human CD34− HSCs in cord blood. Single CD34 negative haematopoietic stem cells (HSCs) can fully reconstitute lympho-myeloid hematopoiesis in mice. Here, using single cell transplantation and gene expression analyses, the authors show that CD34 negative HSCs lie at the apex of haematopoiesis in human cord blood and that they can give rise to erythroid megakaryocytic progenitors.
