Top Open Access Journals In Hematopoietic Stem Cells
Hematopoietic stem
cells (HSCs) are the stem
cells that give rise to other blood cells. This process is called haematopoiesis. This process occurs in the red bone marrow, in the core of most bones. In embryonic development, the red bone marrow is derived from the layer of the embryo called the mesoderm.Haematopoiesis is the process by which all mature blood
cells are produced. It must balance enormous production needs with the need to regulate the number of each blood cell type in the circulation. In vertebrates, the vast majority of hematopoiesis occurs in the bone marrow and is derived from a limited number of
hematopoietic stem
cells that are multipotent and capable of extensive self-renewal.Hematopoietic stem
cells give rise to different types of blood cells, in lines called myeloid and lymphoid. Myeloid and lymphoid lineages both are involved in dendritic cell formation. Myeloid
cells include monocytes, macrophages, neutrophils, basophils, eosinophils, erythrocytes, and megakaryocytes to platelets. Lymphoid
cells include T cells, B cells, natural killer cells, and innate lymphoid cells. The definition of
hematopoietic stem cell has evolved since they were first discovered in 1961. The
hematopoietic tissue contains
cells with long-term and short-term regeneration capacities and committed multipotent, oligopotent, and unipotent progenitors.
Hematopoietic stem
cells constitute 1:10,000 of
cells in myeloid tissue.
