Hematopoietic stem cell

Hematopoietic stem cells (HSCs) are multipotent stem cells that give rise to all the blood cell types including myeloid (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes/platelets, dendritic cells), and lymphoid lineages (T-cells, B-cells, NK-cells). The definition of hematopoietic stem cells has undergone considerable revision in the last two decades. The hematopoietic tissue contains cells 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 hematopoietic stem cells. Here, the HSC compartment consists of a fixed number of different types of HSC, each with epigenetically preprogrammed behavior. This contradicts older models of HSC behavior, which postulated a single type of HSC that can be continuously molded into different subtypes of HSCs. HSCs constitute 1:10.000 of cells in myeloid tissue.
