Hematopoietic stem cells (HSCs) are the blood cells that give rise to all the other blood cells and are derived from mesoderm. They are located in the red bone marrow, which is contained in the core of most bones. They give rise to both the myeloid and lymphoid lineages of blood cells.ymphoid cells include T cells, B cells, and natural killer cells .) The definition of hematopoietic stem cells has changed in the last two decades.
Hematopoiesis: The production of all types of blood cells including formation, development, and differentiation of blood cells. Prenatally, hematopoiesis occurs in the yolk sack, then in the liver, and lastly in the bone marrow. In the normal situation, hematopoiesis in adults occurs in the bone marrow and lymphatic tissues. All types of blood cells are derived from primitive cells (stem cells) that are pluripotent (they have the potential to develop into all types of blood cells). Last Editorial Review: 5/13/2016.
