| Research Abstract |
We have identified human cord blood-derived very primitive CD34-negative hematopoietic stem cell(CD34-HSC) using the intra-bone marrow injection technique for the first time. In addition, we developed a high resolution purification method for CD34-HSC using 18 lineage-specific antibodies and succeeded to identify positive markers of CD34-HSC. Furthermore, we demonstrated that the CD34-HSC seemed to be more immature than the CD34+CD38-HSC. Based on these data, we propose a novel model of human HSC hierarchy.
