Human Stem Cells

CD34+ stem cells are multipotent and can give rise to all cell types in blood. CD34+ cells are most known for expression on hematopoietic progenitor cells found in bone marrow and cord blood. While compromising only 1.5% of bone marrow mononuclear cell population, CD34+ stem cells are responsible for all lymphohematopoietic lineages and are now commonly used clinically as they have been shown to provide long-term durable donor-derived host lymphohematopoietic reconstitution.
