<unk> s <unk> s) are<unk> <unk> s that give rise to all the blood<unk>  types including myeloid (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes/platelets, dendritic<unk> s), and lymphoid lineages (T-cells, B-cells, NK-cells). The definition of<unk> s has undergone considerable revision in the last two decades. The<unk>  tissue contains<unk> s with long-term and short-term regeneration capacities and committed multipotent, oligopotent, and unipotent progenitors. Recently, long-term transplantation experiments point toward a clonal diversity model of<unk> s. Here, the<unk>  compartment consists of a fixed number of different types of<unk> , each with epigenetically-preprogrammed behavior. This contradicts older models of<unk>  behavior, which postulated a single type of<unk>  that can be continuously molded into different subtypes of<unk> s.<unk> s constitute 1:10.000 of<unk> s in myeloid tissue.
